Moire deflectometry and its application in impingement flow field of exhausted jet
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.
