The results of small displacements determination of objects surface by digital holography method are presented. The process of digital holograms recording and phase information reconstruction from the holograms are considered. Measurement accuracy of the normal surface displacement of an object while using two methods of the zero-order diffraction removing is compared with the following phase calculation of object wave.
