Abstract
A video interferogram processor has been developed that uses a standard television camera interfaced to a Z-80 microcomputer to acquire the coordinates of fringe centers. It features single-frame capture with software control of digitization, editing, data selection, and order assignment. A. PDP 11/03 receives the processor data and performs a Zernike polynomial fit from which graphics output is generated.Keywords
