A new simple 3-D laser Doppler system has been developed for simultaneous measurement of the instantaneous velocity vector of a scattering particle. The system is based on the reference beam method. It uses a hologram to generate the reference beams. Only one laser operating in single mode is required as the light source. The system has been tested by measuring all the components of the Reynolds stress tensor in a round cold air jet. The results are presented.
一种新型的简单三维激光多普勒系统已被开发出来，用于同时测量散射粒子的瞬时速度矢量。该系统基于参考光束法。它使用全息图来产生参考光束。只需要一台单模工作的激光器作为光源。该系统已通过测量圆形冷空气射流中雷诺应力张量的所有分量进行了测试。给出了测试结果。
