Design of APV Optics System in Measurement of Flow Field

APV(Adaptive Phase/Doppler Velocimeter)系统基于多普勒频移和多普勒相位差原理，可以自适应地进行微粒的材料识别、微粒的大小及速度测量。本文利用粒子散射理论对APV系统进行了合理地布局，讨论激光多普勒系统在流场测量中光路设计的方法，并通过模拟实验验证该方法的可行性。

The APV (Adaptive Phase/Doppler Velocimetry) system can be used to recognize the particle material and measure the particle size and velocity adaptively according to the Doppler frequency shift and the Doppler phase shift theory. Through the light scattering theory of inconductive spherical particles, the layout of the APV system was studied, and the measurement method of the flow field was discussed as well. The feasibility was proved with the simulated experiments.
