<p>The article installation comprises a lighting device with two light sources (1) and reflectors (2) of which the optical axes are mutually inclined. It comprises pairs of prisms (3, 4) arranged in the optical path and which form two parallel image channels (10, 11) and a resolution objective having an optical configuration (12) of a conventional commercially available projector with means (D) to correct the distorsion of linearly compressed images as well as lenses (A, B, C) for the wide angled projection of the pair of images on a spherical surface. With the optical installation, it is possible by means of a conventional cinematographic projector to project stereoscopically a pair of images compressed in anamorphosis on a very large spherical screen.</p> |
