Abstract
An adapter enables three-dimensional motion photography by means of a single camera, video or film, that includes a single lens system and image pickup. The adapter is engageable to a conventional camera. An optical system within the adapter includes a mirror for detecting a second, distinct perspective of a field-of-view. The two perspective views are orthogonally polarized and applied to a single switchable liquid crystal polarization rotator that is driven by a periodic SYNC signal derived from the camera. A polarization filter receives the output of the rotator which alternately passes perspective views unaltered and rotated by ninety degrees in polarization, providing alternating frames of one or another perspective view to the camera. The stream of alternating perspectives provides a three-dimensional viewing effect when processed by conventional video and film systems.
