A simple, low-cost, versatile holographic scanning system was developed for use with dichromated gelatin holograms or similar high-quality copies made by hologram techniques. The fabrication of the disk holographic scanner is described in detail. The optical configurations of several high-density scan patterns were generated, and they are applicable to commercial scanning requirements.
