OPTICALLY ADDRESSED SPATIAL LIGHT MODULATOR DIVIDED INTO PLURALITY OF SEGMENTS, AND APPARATUS AND METHOD FOR HOLOGRAPHY 3-DIMENSIONAL DISPLAY

摘要

Disclosed are an optical addressing space light modulator which is divided into segments, a holographic 3D image display device thereof, and a method thereof. The holographic 3D image display device comprises: a record light source, an EASLM, a reproduction light source, an OASLM, a scanning optical unit, and a Fourier lens. The record light source emits a record beam. The EASLM modulates the record beam according to the hologram information which is divided into a plurality of spaces. The reproduction light source emits a reproduction beam. The OASLM comprises the segments which modules the reproduction beam according to the hologram information of the record beam by collecting the record beam modulated by the EASLM. The scanning optical unit transmits the record beam to a position which corresponds to the segments of the OASLM. The Fourier lens generates a 3D image by focusing the reproduction beam in a predetermined space.
