Abstract
By simultaneously illuminating an area of a hologram recording medium through an object transparency situated in substantially direct contact with the recording plane of the hologram recording plane with each of two angularly-displaced beams of coherent light, double modulation is achieved. The disclosed technique is particularly applicable to the serial recording on a single hologram of each of a stereo pair of object transparencies, which, on playback, provides a stereoscopic reconstructed image which is directly viewable by an observer.
