Paper Abstract

A system designed to provide a low-cost entry to the area of computer-assisted holo-graphic fringe interpretation, making maximum use of the computational and display capabil-ities of a standard personal computer with a color graphics adapter is described. The system includes a 7MHz video digitizer and four software modules. The software modules provide for video frame capture and storage, rapid analysis of general characteristics, computer-assisted data entry and least squares fitting to a polynomial model, as well as graphic model display and data extraction.
