Paper Abstract

Nongelatin dichromated film (designated as NGD) is a kind of new holographic recording material. To get the eternal hologram with efficient diffraction, low noise, and damp resistance is to seek the optimum technology and conditions at their best of the NGD after exposure. This essay, through a great number of experiments and research, has found a proper optimum technology and conditions after exposure: the pre-processing of the cross-linking accelerant solution, infrared light hardening, swelling colorfast of the basic solution, development of acid solution, water washing, isopropanol dehydrate, and drying with a hot blast. The processing time and PH value of the liquid must be strictly controlled. The NGD hologram through the processing of the optimum technology, has possessed the result of relief and volume hologram. The diffraction (eta) is > 30%, it will not degenerate at the relative humidity of 90%, and can be kept forever at indoor temperatures.
