Paper Abstract

Computer moire deflectometry (CMD) using onegrating, a TV camera and a computer image processor (CIP) was developed. The TV camera is located in a Talbot plane allowing the recording of a (disturbed) image of the grating with maximum contrast and without any other optical component. CIP is used for obtaining, processing, as well as automated interpretation of the fringes. Double exposure, real-time , time-average and phase-measuring methods of CMD for transparent and reflective objects are equally demonstrated.
