In view of the reconstruction problem of stack imaging technology in noisy environment, Lin Nan's team from Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, proposed an innovative method ProPtyNet based on unsupervised physical neural network, which is expected to be applied to chip CD measurement and defect detection. The article was published in Optics and lasers in engin...
Due to the surge in the deployment of small satellites, the increasing congestion of data transmission has always been a persistent problem in the aerospace industry. The collaboration between the Communication and Navigation Research Institute of the German Aerospace Center and Tesat Spacecom GmbH and Co. KG TESAT provides a powerful solution. They successfully developed and tested OSIRIS4CubeSat...
Recently, the Xi'an Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has made significant progress in the field of intelligent spectral environmental perception. Relevant research results have been published in the top journal in the field of environmental science, Environmental Science&Technology (Nature Index, 5-Year IF: 11.7), and have been selected as cover papers....
Topological laser (TL) is an ideal light source for future new optoelectronic integrated chips, designed and manufactured using topological optics principles to obtain robust single-mode lasers. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection are still in the early stages of resear...
On February 11th, global industrial fiber laser giant IPG Photonics announced its financial performance for the fourth quarter and full year of 2024. Annual sales have fallen below the $1 billion mark for the first time, with a year-on-year decline of 24% and a pre tax loss of up to $162 million. As an industry leader, IPG's financial report not only reflects the deep adjustment faced by the ind...
