Abstract:
A stereoscopic display comprising:stereo-pairs display means for selectively displaying stereo-pairs composed of right and left eye perspectives to be observed by observers;observers' face images display means for displaying observers' face images,focusing means operable in conjunction with said observers' face images display means for directing the stereo-pairs displayed by said stereo-pairs display means to right and left eyes of each observer based on the observers' face images displayed by said observers' face images display means, said focusing means being positioned to focus observers' optical images substantially on a screen of said observers' face images display means in geometric agreement with the observers' face images displayed by the observers' face images display means; andtaking means for continuously taking observers' visible light images or non-visible light images focused through said focusing means and adapted to form said observers' face images to be displayed by said observers' face images display means,said stereo-pairs display means being composed of transparent type electro-optical spatial modulation elements disposed between the observers and said focusing means to display the stereo-pairs in time-interlaced state, and said observers' face images display means being composed of a surface light source unit disposed behind said focusing means to display pairs of observers' face images of which flashing regions are inverted with each other in time-interlaced manner, one of each pair of observers' face images displayed by said surface light source unit selectively serving as backlight for said transparent type electro-optical spatial modulation elements so as to be synchronized with the time-interlaced display of said surface light source unit.
