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 (12 - 1 to 12- 7) for executing a wave front conversion are arranged on a non-flat virtual display surface to display the phase distribution into a display position. Each of the modulating units is arranged so that the normal to their surface passes through the display position.
