Abstract

1442757 Luminescence PLESSEY CO Ltd 13 Aug 1973 [18 Aug 1972] 38570/72 Heading C4S [Also in Division G5] An optical apparatus for 3D display and data storage comprises fluorescent material body 7 (liquid or solid), laser 8 (e.g. mode-locked) producing light pulses, an optical arrangement for feeding the pulses to opposite faces of the material, deflectors 13, 14 for defining the pulse positions in two dimensions, and a variable folded optical delay line adjustable for defining in a third dimension a position within the material where pulses intersect and fluorescence occurs. Scanning may be by a rockable mirror or Kerr Cell deflector. Fig. 5 (not shown) includes laser assembly (17) comprising light source (18), variable folded optical delay line (19), mirrors (20), (21) and mode locking device (22) (e.g. a dye cell). The laser may radiate at one frequency for writing and at a different frequency for reading when the material exhibits luminous persistence, the stored information being sampled by an optical detector. To produce improved definition a pulse compressor may be used to provide sub pico second pulses. Fluorescence may be excited by visible radiation, or invisible (e.g. infra-red).
