PDPA-010型激光粒子分析仪是美国国家航空航天局和美空军科学技术研究所协助,由美国航空度量标准公司最近新研制成功的一种粒子测量分析仪。它应用拓扑多普勒原理,能同时测量粒子的速度和大小,能分析通过激光光束交叉点粒子(约12000个/秒)的大小、速度(1维、2维、3维都可以)、密度、流量以及到达的时间。测量粒子粒径:0.5 PDPA-010 laser particle analyzer is a NASA-US Air Force Institute of Science and Technology assisted by the American Airlines Metrology recently developed a new particle analyzer. It uses the principle of topological Doppler to measure the velocity and size of particles at the same time. It can analyze the size, speed (one-dimensional, two-dimensional, three-dimensional) of the cross particles passing through the laser beam , Traffic and arrival time. Measurement of particle size: 0.5
