  • Large holographic memory with plural overlapping detector arrays
    Patent number: 3949235
    Abstract: Relatively large hologram storage plates, e.g., those storing a large number of discrete entries such as character definitions for a large character set, comprise an array of mini-holograms arranged in different memory plate sections.A different photodiode array is associated with each hologram plate section (for efficiency, some elements of different diode arrays may be common). When the stored contents of any mini-hologram are interrogated by a coherent light beam, the stored information is derived via the associated photodiode array and converged (as by OR logic) to memory output terminals.
