Abstract: A camera apparatus and method of use employing a photosensitive photopolymer film as a recording medium for generating an interferogram through the use of a write laser beam and a read laser beam. The interferogram is sensed by a video camera and converted into a digital signal for mass storage or real time display on a video monitor. Because the thin film used is of high resolution and is able to handle a sequence of intefferograms at various video signal processing rates, the camera is able to be employed in real time as a motion picture camera for observing real processes and objects undergoing stress.
