Abstract

The new modified holograms multiplexing method using normal to holographic recording medium reference beam incidence and off-normal signal beams incidence is offered for application in holographic memory having high information capacity and high data rate. Signal beams are located around reference beam concentrically. In this case quantity of multiplex holograms in the same area of recording media is equal to quantity of signal beams. Experimental model of holographic memory applying the offered method was tested. Possibility of multichannel optical head application for data recording and retrieving is shown. Wet photochemical processing is disadvantage of argentum halogenide recording media. Argentum halogenide "PFG-03M" produced by Slavich Company was considered for applying in holographic memory system. Photosensitive layer of "PFG-03M" has thickness ~7-12 μm. The optical scheme of the multiplex holograms record device using a multichannel writing head, where number of channels is equal to number of micro-holograms in the multiplex hologram, is developed. The central part collimated a bunch is used as the basic bunch falling on the photosensitive medium perpendicularly its surface. The peripheral ring part collimated a bunch is distributed by system of mirrors on channels of the multichannel writing head, symmetrized concerning an axis of the basic bunch.
