Resumen: | The signal-to-noise ratio (SNR) of multiplexed holograms of N object waves recorded as volume-phase holograms in bleached silver halide emulsion are experimentally analyzed and compared with those of diffuse-object holograms. We introduce two types of SNR: one belonging to the spatial matrix itself, and the other, the overall SNR, for which the angular range of the matrix distribution was compared with the primary diffuse object. The experimental results obtained show that, even though the same range of spatial frequencies is maintained, the total number of waves that come from the matrix distribution affects the measurements, so the interrelation between the spatial-frequency distribution of noise and the number of storage waves is obtained, and the minimum SNR can be evaluated for diffuse objects. |
