Abstract
A method of contouring three-dimensional objects using an out-of-plane sensitive ESPI apparatus with optical fibers is presented. The contou r map is obtained by shifting the object illumination beam. A Fourier transform method is suggested for automatic quantitative analysis of s pecklecorrelograms in terms of phase. An example of application is pre sented.
