摘要
The optical device comprises a lighting unit with two light sources (1) with reflectors (2), whose optical axes (11) are inclined towards one another, with prism pairs (3, 4) for forming two parallel image channels (10, 11) arranged in the optical path and a supplementary lens arranged after a basic optical (12) of a commercial projector for the lateral expansion of the linearly compressed individual images and lenses (A, B, C) for the distortion-free superwide angle imaging of the image pairs on a spherically curved surface. By means of this optical device, a normal commercially available cine projector can be upgraded to a projection apparatus for stereoscopic, linear anamorphotically compressed image pairs on an extremely large, spherically curved wide- screen surface.
