In this paper, diffraction efficiency for computer-generated hologram (CGH) generated under various conditions was measured. This paper discusses the generation conditions that should be considered in hologram reconstruction. We compared each condition by measuring the intensity of the 1st order diffraction pattern of the fringe generated under the Fresnel condition for the phase and complex hologram.
