✦ Synopsis

In this paper, the resolution of the four interference patterns of the doubly exposed Gabor hologram was investigated. For a small axial shift, the resultant pattern was found to be outside the ΓΏeld of di raction of an Airy's disk of the speckles. As for the other three interference gaps, the patterns for each order of interference were not resolved. The phase shift between these patterns was found to be less than the minimum phase change for the Rayleigh criterion of resolution. Moreover, the di erence in the radii for the patterns at each order of interference was found to be much less than the experimental error.

The visibility of the speckle pattern resulting from the scattered radiation of transmitted beams through a diffusing surface has been studied for a Gabor hologram and speckle photography. The cases of strictly-and quasimonochromatic light are also considered. Mathematical expressions for the depend
