METHOD AND APPARATUS FOR RECORDING PLURAL HOLOGRAPHIC IMAGES INTO A HOLOGRAPHIC RECORDING MATERIAL BY TEMPORAL INTERLEAVING

摘要

Holographic images (I1 to In) are constructed in a recording material (H) in accordance with a temporal interleaving technique in which a first set of images (I1 to In) is constructed for a predetermined first imaging time with a predetermined first time gap being defined between each of the images. Thereafter, in accordance with a subsequent predetermined sequence, a subsequent set of images (I1 to In) is constructed into the same predetermined location. The image sets (I1 to In) have at least one member in common. In one aspect all of the images (I1 to In) are constructed into the same predetermined defined region (R) of the holographic recording material (H) (an angle hologram). In another aspect the predetermined defined region (R) into which each of the images is constructed is separate from all other regions (R) of the holographic recording material (H) (a spatial hologram).
