Making a traditional glass lens requires a lot of experience, skill, and patience grinding a piece of glass to the required shape, and is not for the casual experimenter. Making …read more Continue reading A Fresnel Lens Without The Pain
Scientists in South Korea have created what they call “the world’s smallest ball game,” throwing individual atoms between two optical traps. The research could eventually make for more adaptable and dynamic quantum computers.Continue ReadingCategory: S… Continue reading “World’s smallest ball game” tosses single atoms between light traps
Augmented Reality (AR) promises to relieve us from from the boredom of mundane reality and can also help you navigate unfamiliar environments. Current AR tech leaves something to be desired, …read more Continue reading Smart Contact Lenses Tell You Where to Go
[Raymond Ma] has a penchant for browsing Aliexpress and purchasing curious pieces of hardware that are as high on promises as they are low on cost. This is a process …read more Continue reading What’s Inside a Super-Cheap Projector? Not a Lot!
Fair warning: if you ever thought there was nothing particularly interesting with optical viewfinders, prepare to have your misconception corrected by [volzo] with this deep-dive into camera-aiming aids that leads …read more Continue reading Interesting Optical Journey Results in Hybrid Viewfinder for Smartphones
Scientists in Japan have demonstrated a technique that essentially allows them to remotely control the movements of worms. By implanting light-sensitive proteins into the organisms, the team was able to make them move under green light and stop under U… Continue reading Remote controlled worms can follow stop and go lights
Engineers have set a new speed record for data transmission through a standard diameter optical fiber. By beaming 55 “modes” of signals down a single-core optical fiber, the team was able to transmit at a data rate of 1.53 petabits per second (Pbit/s)…. Continue reading Speed record shattered for data transmission over standard optical fiber
Scientists have demonstrated a powerful technique that will allow quantum computers to store much more information in photons of light. The team managed to encode eight levels of data into photons and read it back easily, representing an exponential le… Continue reading “64-dimensional quantum space” drastically boosts quantum computing
Scientists at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a precisely patterned surface 100 times thinner than paper, … Continue reading Ultrathin metasurface produces web of quantum entangled photons
One of the Star Trek movies has a McGuffin called “transparent aluminum.” While magic mirrors aren’t really transparent, it appears that way to a casual observer. If you haven’t seen …read more Continue reading Magic Mirror Isn’t Transparent Metal
