The multi-channel photon counting system prototype laser lidar developed by 508 Laser Engineering and Technology Research Institute of the 5th Institute of China Aerospace Science and Technology Corporation recently completed the field day and night field tests, marking a breakthrough in the area of ​​laser detection. The traditional laser radar system uses linear detection with low detection sensitivity. Each echo signal needs thousands of photons. The corresponding laser emission has low repetition rate, high energy and few beams, which can only meet the measurement requirements of sparse sampling points. Lidar-based LIDARs increase sensitivity by three orders of magnitude, enabling the ranging to be achieved with only one photon of the echo signal, combined with high-repetition rate, micropulse, multi-beam laser emission and multi-channel photon detection arrays Long-distance three-dimensional imaging. The technical system represents the international development of a new generation of spaceborne laser detection technology trends. Through the prototype development, the breakthrough of the micro-pulse high-frequency laser emission, multi-channel optical fiber focal plane arrays to receive, single-photon detection and processing, high-precision time interval measurement and many other key technologies, the technical level of the domestic advanced level. Stainless products refer to products made from stainless steel, which is
a type of steel alloy that contains at least 10.5% chromium. Stainless
steel is known for its corrosion resistance, durability, and strength,
making it a popular material for a wide range of products. Stainless Products,Aluminum Sheet Metal Parts,Stainless Steel Plate,Carbon Steel Parts Suzhou Gold ant Precision Sheet Metal Co.,Ltd , https://www.jmycutting.com
