Investigation of hologram analyzer with single-component optical hologram matching system

A hologram analyzer is examined in which variable magnification of the image is achieved by placing the holograms in matched planes at close to twice the focal length of the single component optical system. The analyzer is made up of a light source, a rotating diffuser, a focusing lens, two holograms, a spatial filter, a matching lens, a receiving lens, a diaphragm, and the photographic film. The system permits arbitrary orientation of the interference bands with minimum distortions of the interacting wavefronts.
