Interference patterns imaged by an optical system and registered by CCD camera are applied in automatic systems for surface shape and deformation measurements. The digital holographic registration of fringe patterns is proposed to avoid the influence of the optical imaging system. Theoretical relationships and numerical simulation results are presented.
