Renishao collaborated with ASML to meet a range of strict manufacturing and performance requirements and developed a differential interferometer system for providing direct position feedback in metrology applications. Customized encoder solutions can achieve step wise improvements in speed and throughput.Modern semiconductor technology relies on precise control of various processes used in integra...
Researchers from Ming Hsieh's Department of Electrical and Computer Engineering at the University of Southern California have designed the first optical device that follows the emerging optical thermodynamic framework.The work, reported in Nature Photonics, introduces a new way of routing light in nonlinear systems—meaning systems that do not require switches, external control, or digital addressi...
Researchers at the National Institute of Information and Communication Technology in the United States have invented a new structure of a superconducting strip photon detector that can achieve efficient photon detection even in wide strips, and have successfully developed the world's first superconducting wide strip photon detector.The band width of the detector is more than 200 times that of trad...
1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
According to foreign media reports, scientists from the Physics Research Institute and the Institute of Physics and the Center for Quantum Science and Engineering at the Swiss Federal Institute of Technology Lausanne (EPFL) in Lausanne, Switzerland have made a new progress in the field of excitation science, developing a smaller and quieter laser system than previous products.Small laser system (I...
