| Abstract: | This paper presents a method of high sensitivity moire deflectometry.In theory, its priciples of working and measurement are analysed.By using this method in visualization and measurement of flow field in hypersonic shock tunnel,the clear moire deflectogram of the flow field around some special models are obtained and the 3-D density distribution around a cone model with convex is calculated quantitative-ly. |
