Paper Abstract

Many of the properties of dichromated gelatin (DCG) holograms such as diffraction efficiency, spectral bandpass and reconstruction wavelength can be understood by measuring various optical parameters of the DCG film at various stages of the hologram production process. In this paper, the influences of the optical nonuniformity of the substrate and the photosensitive layer, changes in the thickness and the refractive index during exposure and processing, the light transmissivity through the interfaces and absorption in the photosensitive layer, on the hologram properties are investigated and discussed.
