Abstract: 1,199,530. Read-only stores. INTERNATIONAL BUSINESS MACHINES CORP. 3 Dec., 1968 [12 Jan., 1968], No. 57224/68. Heading G4A. [Also in Divisions G2, H1 and H4] An optical AND gate comprises an electrooptic crystal 16, such as KDP, and a transparent photocathode 14 having transparent conductive coatings 20 and 22 disposed as shown in Fig. 1 within a transparent glass envelope 12. In operation, with switch 48 closed, a light beam 42 which may contain an image, such as a photographic memory containing fields of binary bits represented by light and dark spots, is imaged on to photocathode 14, the emitted electrons from which are accelerated by the potential gradient to crystal 16 e.g. light on area 44 causes area 28 on crystal 16 to assume an electron charge thereby developing a potential across the crystal in that area. To read-out the stored electron image, switch 48 is opened, and a plane polarized light beam 26 from digital deflector 24 is scanned across the crystal 16 and directed via beam splitter 30 and analyser 32 to photo-multiplier tube 36 an output voltage being developed across resistor 38 whenever the beam 26 passes through a charged area of crystal 16 which causes the state of polarization of beam 26 to be changed. An electrical signal proportional to the intensity of beam 42 is thus obtained whenever light in area 44 coincides with light on area 28. The stored charge on crystal 16 is erased prior to the next imaging operation by using an electron flood gun 18. The read-out device may function to provide random accessing of information stored on a memory surface such as a photographic film, Fig. 2 (not shown).
