APPARATUS AND METHOD FOR HOLOGRAPHY 3-DIMENSIONAL DISPLAY

摘要

An apparatus includes a recording light source configured to emit recording beams, an electrically addressable spatial light modulator (EASLM) configured to time sequentially modulate the recording beams emitted from the recording light source according to hologram information corresponding to a 3-dimensional image spatially divided into a plurality of portions, an optically addressable spatial light modulator (OASLM) configured to include a plurality of regions corresponding to the plurality of the divided portions of the 3-dimensional image and images on a region corresponding to the portions using the modulated recording beams to form a hologram, a scanning optical unit configured to reproduce the hologram formed by the recording beams serially modulated by the EASLM on a reduced scale and transmit the hologram to the regions of the OASLM corresponding to the portions, and a reproducing light source configured to produce a surface light and emit the surface light to the OASLM.
