Abstract

An analysis of the effects of recording material shrinkage on the quality of reconstructed holographic images is presented. The model presented is for general, slanted gratings formed by a diffracting object beam and a collimated reference beam, as might result when writing a real image hologram of a binary object. It is assumed that, due to the photochemical process involved in the hologram development process, shrinkage occurs along the direction of the strongest recorded grating vector. It is shown that the effect of material shrinkage on the reconstructed image quality, on the optimal read beam angle, and the angular selectivity is proportional to the material shrinkage.
