Multiple recording of holograms with a coded reference wave
Theoretical and experimental investigations were made of the dependence of the quality of a reconstructed image on the ratio of the scales of inhomogeneities of the object and glass-plate diffuser fields. It is shown that the ratio of the signal to the noise resulting from recording of many holograms in one element improves if the random structure of the reference wave field is of the small-scale type. The improvement is proportional to the ratio of the typical scales of inhomogeneities of the object and the reference wave fields.
