Experimental setup for holographic image storage. M’s are mirrors, BS is a beam splitter, is a half-wave plate, L is a lens with the focal length of 150 mm, SLF is a spatial light filter.
Multiple image reconstructions by He–Ne laser. (a)–(j) are the diffraction images from multiple holograms at a single location.
Formation process of multiple volume holograms. Diffractions I, II, and III represent the diffraction efficiencies from the first, second, and third holograms at a single location, respectively. ON and OFF indicate when the writing light is on or off.
