Abstract
This invention provides a stereoscopic image display system that allows a plurality of experiencing persons to visually recognize stereoscopic images by their naked eyes at one time. In correspondence with a distance between eyes of an experiencing person, a plurality of projectors and a plurality of half mirrors are arranged around a periphery of a retroreflective sheet placed horizontally. The respective projectors receive parallax images of an object as a display target which are taken along a circumferential direction of the object. Image light beams (left and right parallax images) emitted from the adjacent two projectors are reflected from the half mirrors and then enter the retroreflective sheet. The two incident image light beams are reflected from the retroreflective sheet in directions of incidence thereof, respectively. The two reflected light beams pass through the half mirrors and then separately enter the right and left eyes of the experiencing person. Thus, the experiencing person can visually recognize a stereoscopic image of the object, which is seen from every direction, at the entire periphery of the retroreflective sheet.
