Abstract

We discuss the color hologram of the human object and previous works with monochromatic reconstruction. A two step method of recording the hologram with reconstruction in white light was suggested in 1975 for monochromatic reconstruction of the image. The transmission hologram with low noise was the first step of this recording. In first experiment we used photo plate 8E75 with bleaching for recording of H1 holograms. Selection of recording materials using signal and noise characteristics is shown. The original method of producing low-noise holograms (SHSG process) for H1 process is discussed. The reflection hologram H2 was produced as the second step. For copying of H1 hologram onto H2 hologram in the first experiment we used He-Ne laser and photo plate PE-2, produced in laboratory (predecessor of plate PFG-03). We will discuss different optical setups for recording H1 and H2 hologram. New problems connected with recording color holograms. In first our work on modeling color holograms was used a method of emulsion thickness manipulation in between exposures and He-Ne laser, then system silver halide -- dichromated gelatin and original silver halide materials with color sensitizing. Characteristics of SHSG process for color silver halide materials are shown. Finally simulation recording color hologram and possible applications demonstrated.
