Paper Abstract

We combine the scan flexibility of computer-generated holographic laser beam scanners with the high diffraction efficiency of volume phase holograms to produce a new type of "holo-scanner." The scanner-hologram consists of numerous, small, volume hologram facets recorded in dichromated gelatin films and produces an arbitrary output pattern with greater than 90% light efficiency. Experimental results for discrete point, continuous line, and 3-D scanners are shown. Multiwavelength and materials processing scanners are also considered.
