Abstract: A stereoscopic viewing system provides stereoscopic viewing using a two dimensional lens system and without having to have two cameras. The system may be used over a wide range of frequencies, in fact all frequencies that can be used for producing or reproducing an image. The viewing system has an opaque leaf positioned between the two dimensional lens system and a camera in a single image path, the opaque leaf is movable laterally in the single image path from a left position to a right position to provide a left image perspective and a right image perspective of the image path to the camera. A switching device moves the opaque leaf between the two positions and retains the leaf stationary in each position for a sufficient time for the camera to view each image perspective.
