Paper Abstract

A method of obtaining surface figure error information from several subaperture interferograms is analyzed, and the effects of roundoff error, digitization error, and fit error are presented. A computer simulation for testing a large flat is shown. This method is applied to average several undersampled interferograms and to analyze lateral shearing interferograms.
