Paper Abstract

It is well known that the macroscopic characteristics describing holographic materials are determined by the physical and chemical processes taking place at a microscopic level during and after exposure and during processing. Very well controlled and systematic measurements have been carried out to determine for the first time the 'complex' nonlinear characteristics of a silver halide material (processed to obtain phase holograms), i.e. to measure its Lin-curves (square-root of diffraction efficiency as a function of bias exposure and fringe visibility) in a range of grating spatial ferquencies. In such a way both the MTF and the nonlinearity of the material can be determined. An analytical function was fitted to the measured data, allowing for the use of these characteristics in the assessment of the quality of the reconstructed holographic image using the method (based on the double Fresnel-Kirchhoff integral) developed by the author.
