DIGITAL HOLOGRAM IMAGE DISPLAY DEVICE

摘要

PURPOSE: A digital hologram image display device is provided to lower the strength of a zeroth order diffraction component without distortion of a restoration target image. CONSTITUTION: A spatial light modulating device(200) realizes a hologram interference pattern of a pattern generating device. A light source(300) irradiates reference light(900) onto the spatial light modulating device. An optical device controls the section of the reference light to irradiate the reference light onto the frontal side of the spatial light modulating device. A diffusion plate(700) is arranged between the frontal side of the light source and the frontal side of the spatial light modulating device.
