摘要：
A method of contouring three-dimensional objects using an out-of-plane sensitive ESPI apparatus with optical fibers is presented. The contour map is obtained by shifting the object illumination beam. A Fourier transform method is suggested for automatic quantitative analysis of specklecorrelograms in terms of phase. An example of application is presented.
