Developing a concentration independent pressure sensing method for high-temperature combustion diagnosis

Recently, the High Power Laser Physics Joint Laboratory of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, proposed a single exposure interferometric calibration method for large aperture diffractive lenses, which provides strong support for the engineering application of large aperture diffractive lenses. The relevant achievements are published in Optics Letters as "...

Vast's Haven-1 program will become the world's first commercial space station, equipped with SpaceX's Starlink laser terminal, providing connections to its crew users, internal payload racks, external cameras, and instruments at speeds of gigabits per second and low latency.Max Haot, CEO of Vast, said: "If you need to provide high-speed, low latency, and continuous Internet connection on the orbit...

Recently, a team of Professor Ruan Shuangchen and Professor Zhou Cangtao from Shenzhen University of Technology proposed for the first time internationally a physical solution based on the generation of attosecond pulses and subperiodic coherent light shock radiation from a superluminal plasma wake field, and explained a new coherent radiation generation mechanism dominated by collective electron ...

Recently, according to the information of the China National Intellectual Property Administration, Zhejiang Sunny Optics Co., Ltd. has obtained a patent named "Optical Imaging Lens", with authorization announcement No. CN221899396U and application date of 2024-01-31.The patent abstract shows that the present application discloses an optical imaging lens, comprising a barrel and first to eighth len...

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...
