An automatic interference pattern processor has been developed for the purpose of rapidly and accurately evaluating either real time interference patterns or interferograms. The system has been designed to provide quick and easily interpretable feedback so that the operator can monitor the system's measurements. The system includes: (1) a semiautomatic mode to facilitate the measurement of difficult interference patterns and (2) an integral, easily used calibration mode. The results of the least squares evaluation are available in a variety of formats.
