Abstract:
1. An optical apparatus for converting a camera or projector to a stereoscopic image capture or projection system, the apparatus comprising: an anamorphic afocal converter configured to halve a field of view of a camera or projector into two optical paths, and convert the halved fields of view into two full fields of view of the camera or projector; a plurality of reflecting elements cooperatively arranged to direct two rectified images at a camera sensor or projection screen, wherein one or more of the plurality of reflecting elements receive the first of the two full fields of view and one or more of the plurality of reflecting elements receive the second of the two full fields of view, and wherein the anamorphic afocal converter is located between the camera or projector and the plurality of reflecting elements; and a weak afocal converter inserted in one optical path to correct magnification differences in the images produced by the two fields of view, wherein the optical path lengths for the two optical paths are unmatched.
