STEREOSCOPIC SYSTEM

摘要

The present invention relates to a stereoscopic projection system that comprises a plurality of stereo-projectors with projection lenses for projecting the left frame as well as a lens for projecting the right frame in order to form stereopair images on a lenticular-raster visualisation screen. The lenticular raster of the visualisation screen separates and focalises these images in the corresponding vision areas of the left frames for the left eyes and of the right frames for the right eyes of the spectators. The projectors include a beam-splitting system for forming a plurality of separate stereo-projections using a plurality of distinct optical systems, wherein each of said optical systems includes two pairs of projection lenses for achieving an individual stereo-projection for a given spectator. The stereoscopic system further includes an automatic corrector connected to a sensor for monitoring the location co-ordinates of the eyes of each spectator. This automatic corrector comprises a lens actuator that performs an optical dynamic combination between the projections of the left and right stereopair images which are focalised by the screen, and the predetermined vision areas of the stereoscopic images for the left and the right eyes of the spectators, respectively.
