Aalyria is establishing a laser link mesh network to quickly transmit data on land, in the air, in the ocean, and in space. The maritime part of the plan is about to be pushed forward.Recently, this DC based laser communication network company announced the signing of a memorandum of understanding with HICO Investment Group, which focuses on investing in shipping and logistics companies. According...
Physicists have been working hard to improve the accuracy of atomic clocks, which are the most precise timing devices currently available. A promising way to achieve higher accuracy is to utilize spin squeezed states in clock atoms.Spin squeezed states are entangled quantum states in which particles work together to counteract their inherent quantum noise. These states provide incredible potential...
Recently, Toshiba announced that in the field of LiDAR lidar for distance measurement, it has developed a technology that can track vehicles, people, and other objects with 99.9% accuracy, achieving the world's highest accuracy. And only using LiDAR to collect data can achieve 98.9% object recognition.In addition, the detection distance in rainstorm and dense fog environments has been increased by...
Superlenses are nano artificial structures that can manipulate light, providing a technique that can significantly reduce the size and thickness of traditional optical components. This technology is particularly effective in the near infrared region, and has great prospects in various applications, such as LiDAR, which is called "the eye of autonomous vehicle", mini UAV and blood vessel detector.D...
An interdisciplinary research group, including the German synchrotron radiation accelerator DESY and the Helmholtz Institute in Jena, Germany, reported that invisible gratings made of air not only are not damaged by lasers, but also maintain the original quality of the beam. The relevant research has been published in Nature Photonics under the title of "Acousto opt modulation of gigawatt scale la...
