- Title

- Abstract
The condition of obtaining undistorted reference fringes when processing a pair of superimposed holograms or photographic images with a constant carrier frequency of bands due to their relative rotation or tilt is obtained. It is shown that the degree of fringe distortion is determined by the combined action of aberrations and the value of the parameter being measured. The technique of an arbitrary tuning of reference fringes is described, which makes it possible to eliminate the relative shift of holograms or photographic images. Experimental results obtained by the optical processing of photographic images of projected fringes are presented.
