Abstract:
Results of research and development of the device for measurement of diffraction efficiency of diffraction optical elements (DOE) simultaneously in many diffraction orders and in the large dynamic range are presented. Two methods of a dynamic range of digital video camera increasing and their technical implementations are considered.

Key words:
Diffractive optics, DOE, computer optics, computer generated holograms, measuring system, image processing.
