Abstract: METHODS AND APPARATUS ARE DISCLOSED FOR INCREASING THE HOLOGRAM STORAGE CAPACITY OF A RECORDING MEDIUM. WITH THE AID OF VARIOUS MASKING TECHNIQUES, EACH HOLOGRAM IS STORED IN A LARGE GROUP OF SMALL AREAS OR VOLUMES
DISPERSED THROUGHOUT THE RECORDING MEDIUM, AND AT LEAST SOME HOLOGRAMS ARE STORED IN DIFFERENT GROUPS.-

Abstract: A first thick hologram of the wave front from an object is formed at a first wavelength to which a first hologram-recording medium is sensitive. A second hologram is recorded on a second recording medium sensitive to a second wavelength by placing the second recording medium adjacent the first and illuminating the first hologram with radiation at the second wavelength. This second hologram can then be illuminated with radiation of the first wavelength to reconstruct with minimum aberration the wave front associated with the object recorded on the first hologram.
Abstract translation: 来自物体的波前的第一厚的全息图形成为第一全息图记录介质对其敏感的第一波长。 通过将第二记录介质放置在第一记录介质附近并用第二波长的辐射照射第一全息图，将第二全息图记录在对第二波长敏感的第二记录介质上。 然后可以利用第一波长的辐射来照亮该第二全息图，以最小像差重建与记录在第一全息图上的物体相关联的波前。

Abstract: A holographic recording medium comprising a hardened gelatin film sensitized with a chromate or dichromate. Exposure effects a change in the index of refraction in the exposed areas of the film, which can then be used without further processing, or washed to remove the sensitizer to make a permanent record.
