This 3D-printed AI construct analyzes by bending light | TechCrunch

https://techcrunch.com/2018/07/26/this-3d-printed-ai-construct-analyzes-by-bending-light/ Machine learning systems, which we frequently refer to as a form of artificial intelligence, at their heart are just a series of calculations made on a set of data. The calculations themselves aren’t particularly complex. Researchers from UCLA show that those calculations can be implemented optically with 3D-printed layers of transparent material, imprinted with

uCameraCube – Hackster.io

https://www.hackster.io/delmans/ucameracube-c64263 Need for a custom camera module. Check out this intetesting looking project. uCameraCube is a parametric camera module build using OpenSCAD uCube library. It is build with Raspberry Pi and Raspberry Pi camera and comes in three versions, which vary in the type of optics used. Thin Lens version M12 Lens version T-Mount version

Fiber visual fault locator videos

Last year I made a posting on Cheap fiber optic visual fault locator. It told about 1mW 5KM Red Light Pen Visual Fault Locator Fiber Optic Laser Cable Tester Meter puts out highly visible red light into a fiber optic cable that has ST, SC and FC optical connectors.The universal fiber connector worked well with single-mode

Physicist Have Created A New Form Of Light That Can Interact Like Atoms | IFLScience

http://www.iflscience.com/physics/physicist-have-created-a-new-form-of-light-that-can-interact-like-atoms/ American researchers have been able to create a three-photon bound state that represents a completely new form of light. As reported in Science, the researchers have been looking at complex interactions between photons for years. They obtained a two-photon state in 2013.

Nanodevice Maps the Angle of Light to Color and Vice Versa – IEEE Spectrum

https://spectrum.ieee.org/nanoclast/semiconductors/nanotechnology/nanodevice-maps-the-angle-of-light-to-color-and-vice-versa  An international team of researchers has added a small twist to typical light filters. They’ve fabricated a nanoscale device that divides incident light into its different component colors based on the direction the light is coming from. They’ve switched from making filters with equally spaced grooves to an aperiodic architecture wherein the grooves are not equally spaced. The research

New Laser Technique Promises Photonic Devices Inside of Silicon – IEEE Spectrum

https://spectrum.ieee.org/nanoclast/semiconductors/optoelectronics/new-laser-technique-promises-photonic-devices-inside-of-silicon When a laser beam modifies a material, those modifications can either be temporary or permanent, and the change can also be either extremely subtle or drastic. The modified material starts responding differently to the laser beam. Scientists have taken advantage of these interactions to create structures within silicon that enable photonic devices. “We can also imagine

They’re still selling incandescent flashlights? | EDN

https://www.edn.com/electronics-blogs/power-points/4458907/They-re-still-selling-incandescent-flashlights-?utm_content=buffer6638a&utm_medium=social&utm_source=plus.google.com&utm_campaign=buffer   The writer of this article assumed that all flashlights would now be LED units, not incandescent, because of many benefits of LED. But in shop roughly one-third of the lights were LED, one-third were halogen, and one-third were incandescent. Why do they still have non-LED flashlights? This article looks for answer to this and teaches about

Fiber optic termination and splicing

We terminate fiber optic cable two ways – with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers. According to Which field-termination method best fits your fiber-optic LAN? article over the

Scientists Have Managed To Store Light As Sound For The First Time | IFLScience

http://www.iflscience.com/technology/scientists-have-managed-to-store-light-as-sound-for-the-first-time/ A team of researchers from the University of Sydney has managed to convert the digital information carried by light waves into sound waves inside a microchip. As reported in Nature Communications, the researchers were able to build a chip that slows down light by turning it into sound waves. “The information in our chip in acoustic

DIY optical power meter with SFP module and Arduino idea

Fifer optics power meter is an important tool for debugging fiber optics networks. I have earlier tested a cheap commercial fiber optic power meter a at Fiber optics power meter posting. Hardware hackers ares famous for building their own test equipment. The basic operation of optical power meter is quite simple: take a suitable detector,
