DEVICE FOR HOLOGRAPHIC IMAGE FOR HOLOGRAMS WITH HIGH DEPTH OF FIELD

摘要

FIELD: image forming devices.;SUBSTANCE: invention relates to image display. Hologram image device has a plurality of holographic panels, each holographic panel of the plurality of holographic panels having a transparent panel encoded by an interference pattern corresponding to the section of the composite hologram image. Device also has one or more light sources configured to emit light and illuminate each holographic panel from a plurality of holographic panels at one or more incidence angle, wherein the interference pattern of each corresponding holographic panel induces a plurality of holographic panels to diffract the emitted light to form a composite hologram image.;EFFECT: technical result consists in enabling increase in the depth of field of three-dimensional holographic images.;15 cl, 7 dwg
