Mei Xin Sheng: The development of high-precision polarized light crown products has been completed

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 "...

The manufacturing of sensors through 3D printing combines speed, design freedom, and the possibility of using waste as a substrate. In the circular economy model, various results have been achieved, and typically discarded residues are used as low-cost resources. A research team in Brazil has proposed a highly creative solution that involves printing electrochemical sensors on fallen leaves. The t...

With the rapid development of modern electronic information technology, integrated circuit chip packaging forms are also emerging in an endless stream, and the package density is getting higher and higher, which greatly promotes the development of electronic products to multi-function, high performance, high reliability and low cost.So far, through hole technology (THT) and surface mount technolog...

The National Institute of Information and Communication Technology of Japan, Nagoya Institute of Technology, and Japan Aerospace Exploration Agency have achieved the so-called "world's first successful demonstration of next-generation error correction codes, reducing the impact of atmospheric turbulence on ground to satellite laser communication".Atmospheric turbulence in ground-to-satellite laser...

Today, VCSELs (vertical cavity surface-emitting lasers) are used in everything from computer mice to face-scanning hardware in smart phones. They are renowned for their ability to integrate seamlessly into semiconductor chips, VCSELs are still considered to be an active field of research, and many researchers believe there are still important applications waiting to be discovered.The laboratory of...
