Paper Abstract

The image quality attainable in producing holographic components depends to a great extend on the optical quality of the holographic recording medium and eventually its supporting substrate. Departure from the assumed ideal optical homogeneity and perfect geometry leads to a loss of image resolution and diffraction efficiency. The problem is analysed by recourse to a wave representation in terms of spatial frequency spectrum. The wedge phase error and the sinuosoidal perturbation are studied. The obtained results permit to derive a tolerance range for the substrate quality. Experimental interferometric methods are presented to the test of holographic plates quality.
