Headdisplay devices such as Apple Vision Pro, Meta Quest, and PICO are expected to completely change the way we perceive and interact with various digital information. By providing more direct interaction with digital information, MR has become one of the key driving forces for the metaverse, spatial computing, and digital twins, and has begun to be widely applied in fields such as intelligent tou...
The most famous use of GPS satellites is to help people understand their location, whether it is driving cars, ships or planes, or hiking in remote areas. Another important but little-known use is to distribute information to other Earth observation satellites to help them accurately locate measurements of our planet.NASA and several other federal agencies, including the US Space Force, the US Spa...
Hybrid 3D integrated optical transceiver. (A, B) Test setup: Place the photon chip (PIC) on the circuit board (green), and glue the electronic chip (EIC) onto the top of the photon chip. (C) It is the cross-section of the EIC-PIC component with micro protrusions. (D) Display the mesh of the finite element model.The latest progress in artificial intelligence, more specifically, is the pressure plac...
Billions of years ago, in a distant galaxy, two black holes collided, triggering one of the most extreme cosmic events in the universe. The power of this phenomenon is so great that it distorts the structure of spacetime, emitting ripples called gravitational waves.These waves will eventually be detected on Earth by the Advanced Laser Interferometer Gravity Wave Observatory (LIGO) detector, and te...
Image source: Federal Institute of Technology in Lausanne, SwitzerlandScience and Technology Daily, Beijing, September 27th (Reporter Zhang Jiaxin) Commercial femtosecond lasers are manufactured by placing optical components and their mounting bases on a substrate, which requires strict alignment of optical components. So, is it possible to manufacture femtosecond lasers entirely from glas...
