Polarization influence on the efficiency, the signal and the noise of bleached silver halide diffuse-object holograms

Abstract

Polarization influence on the efficiency, the signal and the noise of bleached silver halide diffuse-object holograms. The efficiency and the noise of diffuse-object holograms recorded as volume holograms in bleached silver halide emulsion ale experimentally analyzed as a function of the polarization state of the readout wave. An important source of noise found in these holograms when they are processed with rehalogenating bleaches are noise gratings which are very sensitive-polarization. The dependence of signal-to-noise ratio on the relative polarization between the construction and reconstruction beam is shown too. Experimental results are presented which make it possible to choose the best reconstruction conditions for these holograms.
