Abstract

An interferogram analysis system has been developed that uses a standard television camera interfaced to a microcomputer to acquire the coordinates of fringe centers. Following single-frame capture at a resolution of 480 x 512 x 1, continuous lines appear at fringe centers in less than 12 seconds. Editing software provides for the addition and removal of data points and smoothing. Selection of data for analysis and order assignment are under full operator control. The system provides elaborate graphics options based upon a polynomial fit to the data. Under ideal conditions a detailed analysis is obtained in less than 10 minutes.
