STEREOSCOPIC IMAGE DISPLAY DEVICE

摘要

PURPOSE:To allow stereoscopic image display by using a rotary mirror optical system in such a manner that the optical axes of respective elements coincide substantially with the optical axis of an observer. CONSTITUTION:The light crystal space modulating element arrays 101 to 105 having the respective optical axes within the same horizontal plane are successively irradiated with prescribed timing pulses by respective semiconductor laser light source arrays or white light source arrays 301 to 306. The light rays are reflected by the perpendicular plane of a rotationally driven polygon mirror 6 and form multiple images 401 to 406 spaced respectively by DELTA on the front surface of an observation position 5 via an imaging lens 5. The polygon mirror 6 has the perpendicular mirror surfaces of an octahedron and the respective space modulating elements are irradiated with luminous flux pulses. The high-quality stereoscopic images free from flickers when viewed from the observer 5 are obtd. in this way.
