Research of a method and optical system for record multiplexholograms in system of holographic memory

摘要

The new modified holograms multiplexing method using normal to holographic recording media reference beamincidence and off-normal signal beams incidence is offered for application in holographic memory system having highinformation capacity and high data rate. Signal beams are located around reference beam concentrically. In this casequantity of multiplex holograms in the same area of recording media is equal to quantity of signal beams. Experimentalholographic memory system model applying offered method is tested. Possibility of multichannel optical headapplication for data recording and retrieving is shown. Offered multiplexing method advantages consist in following:obviating of the necessity of recording media rotation; crosstalk noise free restored data page images; possibility of thinholographic recording media application.
