ABSTRACT:
A method of scanning a phase image and rapidly converting it into a video signal is disclosed. The phase image is scanned with collimated light such as from a laser and the diffracted light is detected by fixed detectors and converted into a video signal. In a preferred embodiment, multiple color encoded phase images of a full color original are simultaneously scanned, converted into video signals and electronically manipulated to effect real-time full color masking of the original.
