3 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 spatial light modulator divided into a plurality of segments, and a holographic three-dimensional image display device and method using the same. The holographic three-dimensional image display device includes a recording light source for emitting a recording beam, an EASLM for modulating the recording beam emitted from the recording light source according to the hologram information divided into a plurality of regions, a reproduction light source for emitting the reproduction beam, and an EASLM. OASLM comprising a plurality of segments for receiving the recording beam modulated by the modulated and modulating the reproduction beam emitted from the reproduction light source according to the hologram information contained in the modulated recording beam, a plurality of segments of the OASLM recording beam modulated by the EASLM Scanning optical unit for transmitting to a corresponding position among the, and Fourier lens for generating a stereoscopic image by focusing the reproduction beam modulated in OASLM in a predetermined space.
