摘　　要：用傅里叶光学方法从理论上分析了带有滤波器的相干性莫尔偏折法的测量原理,把这种方法用于真实火箭燃气射流冲击场的实验研究.获得了真实火箭燃气射流冲击流场莫尔偏折图.解决了长期以来无法拍摄到高温、高速、强振动冲击、强火焰光的火箭射流流场图像问题.The measurement principle of coherent moire deflectometry with filter is analyzed theoretically by using Fourier optical method. It is used to study the experiment of impingement flow field of real rocket exhausted jet. The moire deflectograms of impingement flow field of real rocket exhausted jet are obtained. So the problem of taking the picture of real rocket jet flow field with high temperature, high valocity, strong vibration and strong flame are solved.
