Recently, the IFA2023 Consumer Electronics Show in Berlin, Germany opened, Hisense exhibited "three-color laser projection family bucket" attracted the attention of media and tourists from all over the world.Since Hisense's young fashion brand Vidda launched a series of three-color laser projection, its accumulation based on three-color laser technology is competing globally and has become a...
Researchers at the University of Illinois at Urbana Champaign have developed compact visible wavelength achromatic mirrors using 3D printing and porous silicon, which are crucial for miniaturization and lightweight optical devices. These high-performance hybrid micro optical devices can achieve high focusing efficiency while minimizing volume and thickness. In addition, these microlenses c...
Physicists from the University of Heriot and the University of Cambridge have developed an innovative laser system called Astrocomb, which can significantly improve the detection of exoplanets. This advanced tool can accurately measure the spectra emitted by nearby stars, which fluctuate due to the gravitational influence of orbiting planets. It is expected that this technology will enhance resear...
Recently, optical semiconductor developer Lumiotive, headquartered in Seattle, USA, launched a new LiDAR sensor LM10, which is its first fully produced product of light controlled metasurface (LCM) technology designed for digital beam steering.The developers stated that compared to mechanical systems, their digital beam steering method overcomes the limitations of traditional LiDAR sensors in term...
The gravitational wave background was first detected in 2016. This was announced after the release of the first dataset by the European pulsar timing array. The second set of data has just been released, combined with the timed array of Indian pulsars, and both studies have confirmed the existence of the background. The latest theory seems to suggest that we are seeing a comprehensive signal of th...
