Abstract
The digital reconstruction of an optically recorded hologram has become a fast developing method and has found a vast practical application in many branches of science and industry. An especially invented diffractive optical element with self imaging properties is placed in the reference beam. In the recording process this element forms its self-image in the hologram plane. Self-imaging properties of the diffractive optical element provide the possibility of recording a digital hologram by means of the phase-shifting without any additional imaging components. The innovation of the proposed method lies in using a self-imaging diffractive optical element which enables a significant simplification of a spatial phase shifting optical setup used to record the digital hologram with only a small decrease of the quality of the reconstructed image.
