Podcasts about optical

Optical networking has spent years as a niche corner of the semiconductor industry. CSI makes the case that the moment for companies like Coherent may have finally arrived — and NVIDIA's two-billion-dollar equity investment in the company suggests the largest chipmaker in the world agrees.Coherent (COHR), is an integrated device manufacturer and base materials supplier specializing in indium phosphide and silicon carbide wafers. Under CEO Jim Anderson, who pulled off a similar business transformation at Lattice Semiconductor, Coherent has been shedding non-core assets and sharpening its focus on data center and communications, which now represents seventy-five percent of revenue and posted forty-one percent year-over-year growth in the most recent quarter. Pro forma revenue growth came in at twenty-seven percent, with gross margins approaching the forty percent threshold that marks a key milestone for IDM-class businesses.The divestitures tell the story of the transformation: a four-hundred-million-dollar sale of the aerospace and defense laser business to private equity, and a fifty-one-million-dollar exit from a materials processing tools segment that was diluting margins. What remains is a tighter, faster-growing business positioned at the intersection of AI data center infrastructure, optical connectivity, and advanced materials.The NVIDIA investment is the centerpiece of this episode. With free cash flow running deeply negative as Coherent scales manufacturing capacity for co-packaged optics and near-package optics expected in the second half of 2026, the company needed capital. NVIDIA needed the optical components. The result was a cash-for-equity arrangement that Nick describes as a more direct version of the warrant-based incentive deals seen at companies like AMD and STMicro, cheaper than diluting shareholders, and cheaper than going to a bank.The silicon carbide segment also draws attention, with five-hundred-million-dollar anchor investments from Denso and Mitsubishi Electric secured when silicon carbide was out of favor, now pointing toward three-hundred-millimeter wafer applications for AI data centers and power grid infrastructure.Q3 guidance calls for revenue between 1.9 and just over 2 billion, gross margin at roughly 41%, and continued negative free cash flow as manufacturing scale-up accelerates. CSI compares Coherent to peer Lumentum — framing COHR as the value play and Lumentum as the momentum play — and confirm they are happy holding both.For in-depth stock research and the Semiconductor Insider membership,visit chipstockinvestor.com.

Most optometric practice owners have no idea how much money they're quietly losing in their optical simply because of merchandising, layout, and the conversations happening—or not happening—between staff and patients.   Welcome to this episode of 20/20 Money: The Business of Optometry. My guest on today's show is Kayla Ashlee. Kayla joins me on the show to talk about the subtle but incredibly powerful levers that influence buying behavior inside the dispensary and why the difference between a thriving optical and an average one often has less to do with pricing and more to do with psychology, presentation, and process.   In our conversation, we discuss the difference between optician-led versus patient-led frame selections, why many owners underestimate the power of suggestion in the optical, and how practices may be unintentionally leaving revenue on the table simply through the way eyeware is presented.. We also talk about practical merchandising strategies that can materially influence capture rate and optical performance without adding more patients to the schedule.   Resources: MassGeneral cafeteria experiment "You will read this first" image Book a Triage call with Adam Download the Practice Owner's Financial Toolkit 20/20 Money Ultimate Financial Success Masterclass OD Mastermind Interest Form Check out Adam's new book: How to Buy an Optometry Practice   ————————————————————————————— Please rate and subscribe to 20/20 Money on these platforms Apple Podcasts Spotify ————————————————————————————— For past episodes of 20/20 Money with full companion show notes, please check out our episode archive here!   Check out Adam's other podcast!   The Optometry Success Podcast  Subscribe on Apple Podcasts: https://bit.ly/4tttng6 Subscribe on Spotify: https://bit.ly/4tuf0YM

That is, more or less, where NASA stood when Artemis 1 left the pad — and where it stands now, with Artemis 2 having put humans beyond low Earth orbit for the first time in half a century. The institutional memory had thinned. The people who built Apollo had moved on, retired, or passed away. The books, as Dr. Alex Polanski puts it in this episode, had to be dusted off. Polanski, a Percival Lowell postdoctoral fellow at Lowell Observatory in Flagstaff, Arizona, joins host Matt to talk about what Artemis 2 actually proved, and why Lowell — an observatory better known for its exoplanet work and its founder's obsession with Mars — has always sat closer to crewed spaceflight than most people realize. The nine Apollo astronauts trained on the volcanic terrain of northern Arizona. They studied lunar maps made at Lowell. They walked the same ground tourists walk today, in the shadow of the Clark refractor. The conversation moves from the geology of the Moon's Highlands and Maria to the meteorite work of Dr. Nick Moskowitz, the mapping happening at the USGS office down the road, and the longer question behind all of it: is the Moon a stepping stone to Mars, or a detour? Polanski makes the case for the stepping stone — not out of caution, but because there are things we don't yet know we need to know, and a one-second light delay is a much more forgiving classroom than a twenty-minute one. And then there's what comes next. Radio telescopes in the craters of the far side, shielded from Earth's noise. Optical interferometers spread across lunar real estate, free of the atmospheric wobble that makes ground-based astronomy feel, in Polanski's words, like reading a note card at the bottom of a pool. For the first time, the possibility of actually seeing the surfaces of other stars. Percival Lowell saw canals on Mars that weren't there. He may have been looking at the veins in his own eye. A century later, his observatory is helping figure out how to look at the real thing.

In this episode, Dr. Steve Vargo sits down with Susan Daly, Head of Optical Products at IDOC, live from IDOC Connection to tackle a challenge every independent optometry practice faces: complexity in the optical. From overloaded frame boards to overwhelming lens options, today's opticals are often suffering from the “peanut butter problem”, too many choices leading to decision fatigue for both patients and staff. The result? Lower capture rates, walking scripts, and missed revenue. Susan shares a practical path forward, showing how simplifying your frame selection, lens offerings, and conversations can increase capture, improve team performance, and create a better patient experience. You will learn: Why fewer choices can lead to more sales How the three-pair presentation drives confident decisions Why confusion, not price, is often the real barrier How to simplify your lens strategy without sacrificing quality A clear framework to communicate value in under two minutes If you want a more efficient, profitable optical that feels easier to run, this episode gives you the blueprint.

rWotD Episode 3262: Optical System for Imaging and low Resolution Integrated Spectroscopy Welcome to random Wiki of the Day, your journey through Wikipedia's vast and varied content, one random article at a time.The random article for Thursday, 9 April 2026, is Optical System for Imaging and low Resolution Integrated Spectroscopy.The Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) is an optical spectrometer at the Gran Telescopio Canarias (GTC) in Spain. It was the first instrument in operation at the GTC. OSIRIS's key scientific project is OTELO.Sensitive in the wavelength range from 365 through 1000 nm, OSIRIS is a multiple purpose instrument for imaging and low-resolution long slit and multiple object spectroscopy (MOS). Imaging can be done using broad-band filters or narrow-band tunable filters with FWHM ranging from 0.2 to 0.9 nm at 365 nm, through 0.9 to 1.2 at 1000 nm. OSIRIS observing modes include also fast photometry and spectroscopy. OSIRIS's field of view is of 8.5×8.5 arcminutes and the maximum nominal spectral resolution is of 5000 for a slit width of 0.6 arcsec. MOS incorporates detector charge shuffling co-ordinated with telescope nodding for an excellent sky subtraction. The use of tunable filters is a completely new feature in 8 to 10 m class telescopes that will allow observing the very faint and distant emission line objects.This recording reflects the Wikipedia text as of 00:54 UTC on Thursday, 9 April 2026.For the full current version of the article, see Optical System for Imaging and low Resolution Integrated Spectroscopy on Wikipedia.This podcast uses content from Wikipedia under the Creative Commons Attribution-ShareAlike License.Visit our archives at wikioftheday.com and subscribe to stay updated on new episodes.Follow us on Mastodon at @wikioftheday@masto.ai.Also check out Curmudgeon's Corner, a current events podcast.Until next time, I'm generative Amy.

Exciting updates from the world of gaming news!

The eyes are the window to the soul… And your heart too?

This has been a rough winter for the world, but especially in for one of Downtown Carlisle's newer business owners. Earlier this year, Civil Eyes'd Optical's building caught fire and is in the process of repairs and being able to open back up. So the DTSB gang of Phil George, Cassie Fourlas, and Cody Myers sat down with Michelle Delp to talk about her journey to get where she is today and how she's weathering the storm. There's a lot of good discussions about how it feels to not be grounded by the stability of a place to go and how she's navigated it by offering to take her work on the road right to the client's house! There's so much good stuff in here and all I know is that we all need to go to Boscov's after this!

A MUST LISTEN PODCAST! This podcast should be mandatory for all archers regardless of where they are currently with their eyesight. Things will change inevitably with your vision and this talk with Chuck Cooley delivers great information on the stages of eyesight reduction, progression, repairs, sight clarity, downrange optic options, eyewear, clarification , variation, ect... You name it, Chuck explains it related to eyesight in the archery industry. Chuck is a highly successful licensed optician, professional archer, former gold medalist, leading lens provider for our sight industry for many years and last but not least a professional person. He dives deeper than I would have thought on this repetitive topic of the evolution of eyesight for marksmen.

This show has been flagged as Clean by the host. We'll explain why we're doing it, what it is, and cover some useful tools along the way. I've been watching movies recommended to me by my colleagues. As I work for a global company, the recommendations are often “Foreign Language”, which by definition is every movie to someone. It's often difficult to read the subtitles, or they are distracting from the acting. So I thought of converting the subtitles to speech for inclusion as an audio track, to produce a Voice Over or Lectoring audio track. Lectoring aka Voice Over Translations First used is soviet countries to read the news and propaganda from a lectors - the first podcasts ? In Polish, lektor is also used to mean “off-screen reader” or “voice-over artist”. A lektor is a (usually male) reader who provides the Polish voice-over on foreign-language programmes and films where the voice-over translation technique is used. This is the standard localization technique on Polish television and (as an option) on many DVDs; full dubbing is generally reserved for children's material. https://en.wikipedia.org/wiki/Lector#Television Example: Night of the Living Dead To give you an idea of what this sounds like I'm going to play you an example of the out of copyright movie, Night of the Living Dead . In the United States, Night of the Living Dead was mistakenly released into the public domain because the original distributor failed to replace the copyright notice when changing the film's name Original First the original sound track, then the same clip with the voice over track. Voice Over Proof of Concept As a native English speaker I find it difficult to follow those Voice Over tracks as I am trying to focus on the underlying audio. In discussions with Polish friends, it seems that this is not a problem when Polish is your native language. To put that to the test I wanted to try it out on a movie to see if that were indeed the case. I asked on Mastodon for a non English movie that was Creative Commons but did have English Subtitles, and HPR host Windigo had the answer. 2009 Nasty Old People is a 2009 Swedish film directed by Hanna Sköld, Tangram Film. It premiered on 10 October 2009 at Kontrapunkt in Malmö, and on file sharing site The Pirate Bay. The film is available as an authorized and legal download under the Creative Commons license CC BY-NC-SA. So my idea was to take each bit of subtitle text, convert it to audio, then have the generated audio play at the same time the subtitle appears on the screen. We use piper to process shows here on HPR, and we also generate srt, or SubRip subtitle files for each show. SRT or SubRip files are the easiest subtitle file to work with. From https://en.wikipedia.org/wiki/SubRip The SubRip file format is described on the Matroska multimedia container format website as “perhaps the most basic of all subtitle formats.” SubRip (SubRip Text) files are named with the extension .srt , and contain formatted lines of plain text in groups separated by a blank line. Subtitles are numbered sequentially, starting at 1. The timecode format used is hours:minutes:seconds,milliseconds with time units fixed to two zero-padded digits and fractions fixed to three zero-padded digits (00:00:00,000). The comma (,) is used for fractional separator . A numeric counter identifying each sequential subtitle The time that the subtitle should appear on the screen, followed by –> and the time it should disappear Subtitle text itself on one or more lines A blank line containing no text, indicating the end of this subtitle I downloaded the movie from the Internet Archive , and then used Piper voice to convert a minutes worth of subtitles. piper_voice: A fast and local neural text-to-speech engine that embeds espeak-ng for phonemization. GPL-3.0 license Once I had the audio prepared for a sample of the subtitles, it was over to audacity to create a new subtitle audio track. Audacity is the world's most popular audio editing and recording app GPL v2 or later, Timing the segments would be a problem, if it were not for the fact that Audacity supports srt files as Labels. File > Import > Lables. Then select the srt file The subtitle track with the text of the audio will be displayed. I could then Import each Audio segment and line them up with the subtitle track for to get the correct timing. Each subtitles segment created a new separate audio file which I then exported. I then used Kdenlive to open the video and import the audio and subtitle tracks. Kdenlive: is the acronym for KDE Non-Linear Video Editor. It works on Linux, Windows, macOS, and BSD. GPL-3.0-or-later There is a good article on adding by Jean-Marc on How to Add Subtitles Easily in Kdenlive Project > Subtitles > Add Subtitle Track Select the Subtitle file Align the subtitle and audio track. After rendering the segment out I was satisfied that this was something worth doing. The script The script can be found on the episode page for this show on the HPR site, and I put it together as a proof of concept. It creates a new audio track for the subtitles, and merges this with the original sound track to create a new selectable sound track. It begins by creating a length of silent audio that is as long as up to the first subtitle time segment begin timestamp. The first subtitle segment is converted from text to speech using Piper voice That segment of audio is added to the initial silence track. We check the total length so far, and then see if there is supposed to be silence between the last and next subtitle segment begin timestamp. If there is, then a filler piece of silence is added until the next subtitle should appear. If not then the audio for both subtitles play immediately after one another. I was worried that the subtitle audio would then lag behind the on screen dialogue but it works surprisingly well. Even long series of dialogue sort themselves out after a bit. We do this over and over again for each subtitle, right up to the very end of the movie. This new subtitle to speech audio track is then merged back into the media file as a new audio track. 96 00:15:06,240 --> 00:15:10,640 It will be two years before it's this big 97 00:15:12,840 --> 00:15:17,840 But don't you bother. By then I'll be long gone 98 00:15:19,840 --> 00:15:22,400 It was just a question 99 00:15:22,880 --> 00:15:25,480 Porridge? Original First the original sound track, then the same clip with the voice over track. Voice Over Lessons learned Now that I have done this for a lot of movies, there a few tips for getting the best output. The creation of the audio track usually goes well, but you can run into issues with the merging of the new track back into the movie. Preparation The first thing you need is a subtitle file which will be the basis of the voice you will be listening to. It should be good quality so that it matches when the actors speak. It's important to clean up this before you use it, fixing spelling mistakes and removing html that will get rendered. Listening to three hours of “I L Zero ve y Zero u”, or “less than forward slash I, greater than”, or “L am from Lndia” can get a bit tedious. You should also try and get versions that translate the songs as well. Getting a SRT file from the media. As many Subtitles are taken from a DVDs they can often be poor Optical character recognition versions of the bitmap-based streams. So a picture of string “Hello World” rather than the letters. ffmpeg By far the easiest and best way to get the subtitles is to extract it from the movie itself, provided it's a separate track. ffmpeg is a complete, cross-platform solution to record, convert and stream audio and video. LGPL-2.1-or-later, GPL-2.0-or-later https://ffmpeg.org/ ffmpeg -y -hide_banner -loglevel error -txt_format text -i "${this_movie_file}" "${this_srt_file}" Getting a SRT file from the web. If that fails you can try to get the subtitle files from the Internet. https://www.opensubtitles.org Select your language with the highest subtitle rating. You can check the media using the mpv media player. mpv is a media player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types. GPLv2+, parts under LGPLv2.1+, some optional parts under GPLv3 https://mpv.io/manual/master/ Name the srt file with the same prefix as the movie and mpv will play it. You can also use the --sub-files= option as well. mpv "${this_movie_file}" --sub-files="${this_srt_file}" Scrub through the file to see if the timing is correct. The subtitles can be toggled using the j key. Fixing Timing issues It's very important to get the subtitles to align, otherwise the voices will be out of sync. When the subtitles don't match up, it's usually that they need to have the start offset corrected. ffsubsync will automatically try and adjust the offset of the first subtitle to the first use of speech in a movie. ffsubsync: Language-agnostic automatic synchronization of subtitles with video, so that subtitles are aligned to the correct starting point within the video. MIT license https://github.com/smacke/ffsubsync pip install ffsubsync ffs video.mp4 -i unsynchronized.srt -o synchronized.srt LosslessCut will allow you to quickly remove additional trailers, or ads, at the beginning, so that ffsubsync will have a better chance of working if they are trimmed away. LosslessCut: aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. GPL-2.0 license https://github.com/mifi/lossless-cut If that fails to match up the subtitles, you can use mpv keyboard shortcuts , move to the first speech segment an then press the Ctrl+Shift+Left and Ctrl+Shift+Right to adjust subtitle delay so that the next or previous subtitle is displayed. It will also show a number giving the miliseconds the delay is, eg -148416 miliseconds or -148.416 seconds. You can use many tools to adjust the subtitles, and I tried out SRT Offset . srt-offset: A simple command-line tool to offset SRT subtitle files. This tool allows you to adjust the timing of subtitles in SRT files, which can be useful when subtitles are out of sync with the video. MIT license srt-offset -i input.srt -offset -148.416 -o output.srt Manually adding the new subtitle to speech audio track If that presents an issue then you can use avidemux to just add the new audio track. Avidemux: is a free video editor designed for simple cutting, filtering and encoding tasks. GPL V2 Open Avidemux, and select “File > Open”, to select the movie. Then go to “Audio > Select Track” Select the next unselected track and tick “Enabled”, “Add Audio Track” Then pick the new mixed track, in this example .~NastyOldPeople_mixed.mp3 Conclusion I now find it much easier to watch a movie with the voice over track. It gets to a point where I don't even notice it is there and just hear the actors speak in their own language, and I just know what they are saying.

Innocenzi C, Pavone M, Seeliger B, et al. Diagnostics 2026.Episode Summary:In this journal club deep dive, we explore a groundbreaking 2026 systematic review that challenges the traditional intraoperative frozen section. We examine how hyperspectral and multispectral imaging are fundamentally reshaping the operating room by giving surgeons real-time, molecular-level vision. What happens when we can see beyond the visible spectrum, and how do we navigate the philosophical boundary between human surgical intuition and artificial intelligence?In This Episode, We Cover:• The End of the "Frozen Section" Waiting Game: Why current intraoperative pathology wastes precious surgical time and how "optical biopsies" provide cellular-level insight without the need for tissue contact, contrast agents, or freezing.• The Science of the Spectral Fingerprint: Moving beyond standard RGB monitors that limit what surgeons can see. How malignant tissues interact with light—through refraction, scattering, absorption, and fluorescence—to create unique optical signatures that our naked eyes completely miss.• Entering the Hypercube: How the 3D data sets of spectral imaging are captured: ◦ Spatial & Spectral Scanning: High-resolution methods that unfortunately struggle with breathing patients, making them susceptible to motion artifacts. ◦ Snapshot Technology: The real-time, video-rate method that balances spatial and spectral resolution for live clinical use.• Clinical Showdowns - Cervical and Ovarian Cancer: ◦ Cervical Neoplasia: How multispectral imaging tracks the dynamic whitening of tissue following acetic acid application, plummeting false-diagnostic rates to an astonishing 1.7% compared to the 20-24% error rates of traditional methods. ◦ Ovarian Cancer: The massive hurdle of surgical blood acting as an "optical sink" that confuses sensors by causing spatial heterogeneity, and how mathematical normalization techniques correct these specific errors. ◦ The Falloposcope: A look at miniaturized technology safely navigating the fallopian tubes, combining optical coherence tomography (OCT) and multispectral imaging to detect early-stage cancers right where they originate.• The "Black Box" and Spurious Correlations: Why feeding complex hypercube data into AI models (like CNNs and Random Forests) can be dangerous if the data sets are unbalanced. If an algorithm learns to diagnose cancer based on a spurious correlation like the glare of an OR light rather than actual biomolecular tumor markers, it will fail in new environments. We discuss the absolute necessity of Explainable AI (XAI) so surgeons can trust the biological plausibility of the machine's decisions.Key Takeaway: The integration of hyperspectral and multispectral imaging serves as a real-time optical biopsy, offering incredible sensitivity for detecting malignancies. By pairing these tools with transparent, explainable AI, we are standing on the precipice of a new era that will drastically improve patient outcomes and force us to redefine the future of surgical intuitionSupport the showGet the "Digital Pathology 101" FREE E-book and join us!

Astronomy Cast Ep. 782: Luminous Fast Blue Optical Transients By Fraser Cain & Dr. Pamela Gay Streamed live on Feb 13, 2026. Modern astronomy has found that the Universe can surprise us. Here's one which astronomers have called Luminous Fast Blue Optical Transients. They're kinda like supernovas, they're kind of like gamma ray bursts, but they're not like them. So what are they? In the distant Universe, are blue light flashes, bright and hard to understand. These objects, uncreatively named "Luminous Fast Blue Optical Transients," are just the kind of puzzle astronomers love. In this episode, we look at their discovery and our current understanding of what they might be.

If your optical felt different in 2025, you weren't imagining it.  Across the country, practices saw capture rates slip, exam-onlys rise, and patients walk out the door with a fresh refraction, buying absolutely nothing. We know this isn't temporary, so the Power Hour is not waiting it out, we're getting proactive.  This week, Eugeneand Kayla Ashlee, CEO of Spexy, collaborate againbecause she is obsessed (in all the best ways) with the real levers that move optical revenue. Unlike most conversations about capture rate, she helps her clients go far beyond pricing and "consumer sensitivity." Leveraging the data points from real practices she works with, Kayla breaks down human influence, retail science, merchandising psychology, and the subtle behaviors inside your practice that are pushing patients away instead of drawing them in. 

@Christadelphians Video: Description: The 12 foundations of the city walls are made of 12 stones that reflect pure light. All light we see is reflected, but isotropic materials don't affect polarised light, whereas anisotropic materials do. All the stones mentioned in Revelation 21 for the foundations are anisotropic which means when pure polarised light shines through them they are colourful. God looks on the heart with pure light, so the glory of God is reflected in us as living stones as the foundation to build the saints who are the temple of the living God.# SummaryThe video explores the significance of the 12 specific jewels chosen by God for the foundations of the city walls in Revelation 21, emphasizing their unique properties and spiritual symbolism.# Highlights-

Listen to 144 Future Now Show  Bobby is on the road this week, but we do hear from him briefly. There are some fascinating developments of late, including the development of 100x faster and much cheaper optical computing, biomimicry applied to making a painless needle and cheap non-clogging micro printer nozzles from a mosquito’s probiscus, a fish filter for sifting out microplastics from your washing machine.  Meanwhile NASA has lofted a massive high altitude helium balloon into the Stratosphere above the Antarctic, to study the weather and to look for evidence of the elusive Dark Matter, yet to be seen physically. And a motherload of lithium has been discovered in a volcanic caldera on the Nevada Oregon border, enough to create Lithium based batteries for dozens of years, freeing us from the tyranny of other countries controlling the supply.  We conclude with a fascinating exoplanet discovery where the atmosphere potentially rains diamonds!  And Merry Christmas, Happy Hanukkah and New Year to you!
