With the increasing demand for human data, the requirements for data storage methods are also increasing. Optical Data Storage (ODS) is a light based storage method commonly used in DVDs, which is low-cost and very durable. But ODS usually stores data in a single layer, and the amount of data that can be stored is limited. Gu Min, academician of Shanghai University of Technology, Wen Jing, and Rua...
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...
AbstractDue to the width of the laser melt pool and the sintering effect on the surrounding powder, the experimental size of the selective laser melting (SLM) sample will be larger than the design size, which will greatly affect the dimensional accuracy and surface quality of the thin-walled sample. In order to obtain SLM thin-walled TC11 specimens with precise dimensions, an orthogonal experiment...
IntroductionIn recent years, inspired by insect compound eyes, artificial biomimetic compound eyes have shown great advantages in overcoming the limitations of existing imaging devices such as large, bulky, and heavy, and improving the performance of medical endoscopy, panoramic imaging, micro navigation, and robot vision due to their unique optical imaging solutions such as small size, distortion...
For the first time, researchers at Umeå University, Sweden, have demonstrated the full capabilities of their large-scale laser facility. The team reports generating a combination of ultrashort laser pulses, extreme peak power, and precisely controlled waveforms that make it possible to explore the fastest processes in nature.Umeå’s laser is 11 m long and generates very short pulses László Vei...
