Abstract: A system for scanning an amplitude or a phase image and rapidly converting it into a video signal is disclosed. The image is scanned with a focused light beam such as from a laser and the information-modulated light is detected by fixed detectors and converted into a video signal which may then be electronically processed. The method is capable of performing in a scanning mode the same optical processing as is performed by conventional partially coherent optical processing systems. This novel method provides a video signal which represents the processed image. A particularly preferred embodiment comprises simultaneously scanning multiple color encoded surface deformation phase images which together represent a full color original object and generating simultaneously the three video signals that represent the primary colors (red, green and blue) of the original object.
