Laser Doppler Anemometry(LDA)is a device to measure of tracer particles through the probe laser Doppler signals, and then gain the speed by the relationship between speed and the Doppler frequency.
“激光多普勒测速仪(Laser Doppler Anemometry, LDA)是测量通过激光探头的示踪粒子的多普勒信号，再根据速度与多普勒频率的关系得到速度。”最简练的翻译如下:LDA measures Doppler signals of particle-tracing by laser detector, and velocity r
