STEREOSCOPIC DISPLAY APPARATUS

摘要

A space light modulating apparatus and a stereoscopic display apparatus which are used in a rewritable hologram stereoscopic display. A solid image can be properly displayed by a phase distribution of a low spatial frequency. A plurality of flat space light modulating units each having a predetermined area for converting a wave front conversion while setting a position near the position of a cross point (center position) of a normal line from a virtual display surface of a non-flat shape to display the phase distribution into a producing position of a solid image are arranged along the virtual display surface such as cylindrical surface or spherical surface.
