APPARATUS FOR HOLOGRAPHY 3-DIMENSIONAL DISPLAY

摘要

PURPOSE: An apparatus for holography 3-dimensional display is provided to implement 3-dimensional hologram images in full colors, by making chromatic lights be incident on a hologram playing part at a surface plasmon forming angle per color by a sheet light source unit of which structure is slim. CONSTITUTION: An apparatus for holography 3-dimensional display(10) includes a hologram playing part(60), a light source(30) and a sheet light source unit(20). The hologram playing part generates surface Plasmon in response to an incident light, and implements 3-dimensional images by making the generated surface Plasmon diffracted by hologram. The sheet light source unit implements colors by adjusting an incident angle on the hologram playing part in order to generate each surface Plasmon as to a plurality of color lights respectively. The sheet light source unit includes a light waveguide plate(50). The light waveguide plate emits the incident light through a light emitting plane.
