Paper Abstract

The survey of main trends in holographic study of the surface shape for diffusely reflective objects is made in the paper. These methods are the basis for the different methods for direct contour mapping of deviation in shape of the object under study from the master one. The description and comparison of these methods and technique is done in the paper. The dependence of the resulting contour map contrast on the shift of the speckle fields of object and reference wave between the exposures is calculated.
