Abstract

In this paper an algorithm of rapid fringe thinning is presented. It consists of fringe smoothing and skeleton extracting. The pulsed noise and `barr' in the fringes can be restrained effectively and the `hole' in the fringes can be padded. Some applications of the method to interferograms of explosive flow field and hypersonic shock tunnel flow field are also presented.
