Abstract
Abstract An optical relay is disclosed for use in an imaging system for the purpose of providing special visual effects. In the preferred embodiment, the relay is used to transfer the aperture stop within a camera lens to a location where the light can be modified by appropriate color filtration for anaglyph stereoscopy. For example, the relay may be interposed between the taking lens and body of a camera, and may include a field lens for transferring the aperture stop plane of the taking lens to the central plane of a lens assembly adapted to form an image at an image plane within the camera. The anaglyph color filters and a special iris are positioned near the aperture stop image plane of the lens assembly. The iris is adapted to restrict the light path in essentially only one dimension (vertically) so that, regardless of the amount of light traversing the system, full stereoscopic information is retained.
