By Max Planck Institute for the Structure and Dynamics of Matter February 4, 2023A magnetic material is exposed to two laser beams whose electric fields turn in opposite directions. The material scatters back the light. If there is a difference between the intensity of the scattered light from the two beams, the material is in a topological phase. Credit: Jörg Harms, MPSDTopological phases are not limited to electronic systems and can also exist in magnetic materials characterized by magnetic waves, known as magnons.…

Lumus Z-Lens shrinks the optical engine by 50% compared to the company's current Maximus technology. Image: LumusThere is a key difference, though: Z-Lens only offers 3,000 nits/W compared to over 4,000 thanks to the larger optical engine in Maximus. However, the company maintains that this is a conservative estimate and still sufficient for daylight usage: "To achieve a better aesthetic (by allowing for a smaller projector), we took a slight hit on the brightness. I would, however, make a couple of points on this:…

Mehul Reuben DasJan 02, 2023 18:36:26 ISTThe Peking University in China has unveiled its plan to build the largest optical telescope in Asia and close the gap in astronomy capabilities with the rest of the world. This move comes amidst China’s expanding space programme after being shut out of global space collaborations at the behest of NASA and being left in isolation for years. Representational Image.

Illustration of the laser interrogation of a highly charged ion clock (artwork). Credit: PTBThe scientists of the QUEST Institute at PTB have developed and tested a new type of optical atomic clock.Highly charged ions are a form of matter that is commonly found in the cosmos, such as in the sun or other stars. They are called “highly charged” because they have lost many electrons and therefore have a strong positive charge.As a result, the outermost electrons in highly charged ions are more strongly bound to the atomic…

LG is all set to showcase its breakthrough telephoto camera for smartphones at its Consumer Electronic Show (CES) 2023. The consumer goods manufacturer has…

LG has developed a breakthrough new telephoto camera component for smartphones that will allow users to zoom in from long distances without loss in picture or video quality. The company announced their Optical Telephoto Zoom Camera Module on Tuesday, explaining that the new zoom lens will adopt similar telescopic functions as a DSLR camera, resulting in clean image quality even when transitioning to 4x or 9x zoom ranges. LG Innotek, LG's electronic components subsidiary, said that the company will do a full reveal of the…

Today’s high-end smartphone cameras still rely heavily on computational imaging for some telephoto shots, but LG subsidiary LG Innotek looks set to change that with its new optical zoom camera technology. Set to be officially unveiled at CES 2023 in early January but teased by the Korean company this week, the technology paves the way for improved image quality for zoom captures. The module’s compact design will also free up more space inside the phone — perhaps for a bigger battery or even a larger image sensor —…

LG may not make smartphones anymore, but it's still building components for them. The company's LG Innotek arm just unveiled a periscope-style true optical zoom camera module with a 4-9 times telephoto range. That would allow smartphone cameras to retain full image quality through the entire zoom range, while potentially reducing the size and number of modules required.  Samsung developed a similar camera module, also known as a "folded" lens, with a four times zoom first used in the Galaxy S20 Ultra smartphone. LG…

just dropped from $100 to only $50. Featuring 15 programmable controls including six thumb buttons, you can program every button to cater to your needs. The Hero 25K DPI sensor allows for extremely precise control for those sniping moments or detailed design projects. This accuracy also stems from the Lightspeed wireless technology operating at a 1ms response time, too.Underneath the mouse, you'll find Optical technology that uses LED lights to scan the surface underneath the mouse for that response time. Because it's…

Telecom regulator TRAI on Monday suggested that the Department of Telecommunications should approach the defence ministry for accessing part of its optical fibre network or suitable bandwidth to extend telecom coverage in the far-flung areas of Himachal Pradesh.The regulator recommended that in four districts — Lahaul and Spiti, Mandi, Kullu and Chamba — the villages that are yet to be connected under BharatNet Project should be immediately connected on VSAT media that can be surrendered as soon as the optical fibre cable…
