Abstract

Silver-halide sensitized gelatin has the sensitometric and spectral response of silver halide emulsions and the holographic characteristics of dichromated gelatin, and therefore when properly processed it has little scattering and absorption. Silver-halide sensitized gelatin is one of the most promising techniques today for the fabrication of transmission holographic optical elements. In this paper we will first review the mechanism of hologram formation in silver halide sensitized holograms. The most important steps of processing -the influences of the developer on the modulation transfer function and of bleaching on the difraction efficiency- will be analized. Holographic characteristics such as exposure sensitivity, resolution, thickness change and evironmental stability will be pointed out. Through optimized processing we have been able to fabricate holographic optical elements, including a holographic scanner and different off axis holographic lenses. These will be analyzed from the point of view of the recording material.
