Abstract
A new configuration holographic memory with a one-beam geometry in a photorefractive crystal has been proposed, and recording of ten angle-multiplexed holograms in a Fe:LiNbO3 crystal has been experimentally demonstrated. A maximum page number of 1728 pages in the LiNbO3 crystal was theoretically estimated by the angular multiplexing method at an incident beam diameter of 5.10 mm and the laser wavelength of 514.5 nm. In this new configuration, one incident beam can simultaneously play two roles as an object beam and a reference beam, therefore, an optical setup becomes simpler than conventional setups, which leads to compact and robust holographic recording system.
