POLARIZATION INFLUENCE ON THE EFFICIENCY, THE SIGNAL AND THE NOISE OFBLEACHED SILVER-HALIDE DIFFUSE-OBJECT HOLOGRAMS

Polarization influence on the efficiency, the signal and the noise of bleached silver halide diffuse-object holograms. The efficiency and th e noise of diffuse-object holograms recorded as volume holograms in bl eached silver halide emulsion ale experimentally analyzed as a functio n of the polarization state of the readout wave. An important source o f noise found in these holograms when they are processed with rehaloge nating bleaches are noise gratings which are very sensitive-polarizati on. The dependence of signal-to-noise ratio on the relative polarizati on between the construction and reconstruction beam is shown too. Expe rimental results are presented which make it possible to choose the be st reconstruction conditions for these holograms.
