Computer Synthesis of Holograms and Spatial Filters

  • B. R. Brown
Conference paper

Abstract

The computer generated hologram is a popular outgrowth of efforts to develop spatial filters for coherent optical data processing systems. Needless to say, the intense coherent light produced by lasers made possible the use of spatial filtering systems for processing pictorial information; however, versatility of such systems initially was restricted because only a few filter functions could be produced by conventional interference holography. Now there are several techniques employing digital computers to synthesize filters with an arbitrarily general complex transmission function.
