Abstract
The present disclosure relates to a digital hologram display device in which the 0th diffraction component is removed for optimizing the reproduction and replay of three-dimensional hologram video data. The present disclosure suggests a digital hologram image display device including a pattern generator generating holography interference patterns; a spatial light modulator receiving the holography interference patterns from the pattern generator and representing the holography interference patterns; a light source positioning at one side of the spatial light modulator and illuminating a reference beam to the spatial light modulator; an optical device controlling the reference beam to be collimated onto the entire surface of the spatial light modulator; and a diffusion sheet disposed between the light source and the spatial light modulator.
