ABSTRACT:
An improved stereoscopic image displaying system is disclosed. A pair of adjacent image displaying means generate a stereoscopic pair of images. A semitransparent mirror and two polarizing filters merge the two images in the same virtual space and impart distinctive polarization to light rays carrying the two images displayed. A louver type filter suppresses the residual view generated by one of the displaying means. The louvers will allow only the image reflected on said semitransparent mirror to pass. A second louver type filter compensates the attenuation that the first louver type filter has introduced, in such a way that the two combined images are of adequately similar intensity. A user wearing polarizing spectacles can see a clear stereoscopic image from a variety of angles.
