Using light beams for communication is not a new idea, even outside of Star Trek, Star Wars, and other similar fantasy stories. Scientist and science fiction writer Arthur Clark predicted that beam communication, at that time modern satellite communication was just a dream.In 1975, the magazine published an article about laser communication or laser communication equipment. The demonstrati...
Researchers from Opole University of Technology in Poland have reported the latest progress in studying the effect of post-processing methods on the fatigue performance of materials prepared by selective laser melting (SLM). The related research was published in The International Journal of Advanced Manufacturing Technology under the title "Influence of post processing methods on fatigue performan...
Recently, the team of Professor Sun Jinhua and researcher Wang Qingsong of the University of Science and Technology of China and the team of Professor Guo Tuan of Jinan University have made important achievements in the field of early warning of thermal runaway optical fiber detection of lithium-ion batteries.A high-precision, multi-mode integrated fiber optic device that can be implanted in...
By using a new type of laser, the processing speed of wafers can be 10 to 20 times faster than before. This is the result of a research project at the Fraunhofer Institute for Solar Systems in Germany.Researchers have developed a prototype that can use ultraviolet waves to carve the most intricate structures on silicon wafers. The new system concept enables solar cell manufacturers to perform lase...
ABB has signed a third contract with the global leader in high-resolution space greenhouse gas monitoring, GHGSat, to manufacture optical sensors for its C12, C13, C14, and C15 satellites. It is reported that C12, C13, C14, and C15 satellites are scheduled to be launched into orbit in 2024.These new satellites will join GHGSat's expanding constellation for detecting and quantifying industrial gas ...
