Paper Abstract

The sensitivity and the diffraction efficiency of the Lippmann hologram recorded in methylene blue sensitized dichromated gelatin increases for red light when the moisture of the plate is properly controlled during the exposure. The exposure required to obtain the diffraction efficiency of 70% is 25OmJ/cm2 for 45% moisure for 647.lnm red light. The photochemical reaction of the plate is briefly discussed and the experimental results of multicolor recording using this method are presented for Lippmann hologram.
