Stereoscopic imaging arrangement and viewing arrangement
First Claim
1. A stereoscopic image arrangement comprising (a) an optical device having an objective and further lens means located remotely from, but in the optical path, of the objective and (b) a stereoscopic imaging device arranged to receive light from said further lens means and form an image on a photosensitive image plane, the stereoscopic imaging device having shutter means arranged to selectively occlude light exiting from left and right regions of said further lens means to form right and left images on said image plane and having means for combining said right and left images to form a stereoscopic representation of the field of view of said objective, wherein said shutter means comprises an array of more than two optical shutter elements distributed from left to right and control means for controlling the light transmission of said optical shutter elements so as to vary the stereo base width between said right and left images and to vary the size of the unoccluded left and right regions of said further lens means to vary at least one of the depth of field and the illumination at said image plane.

Abstract
A stereoscopic imaging arrangement comprises a) an optical device (1) having an objective (2) and further lens means (3) located remotely from but in the optical path of the objective and b) a stereoscopic imaging device (4) arranged to receive light from said further lens means and form an image on a photosensitive image plane (7), the stereoscopic imaging device having shutter means (5) arranged to selectively occlude light exiting from left and right regions of said further lens means to form right and left images on said image plane and having means for combining said right and left images to form a stereoscopic representation of the field of view of said objective. The image may be displayed on a monitor (9) and viewed stereoscopically with switching spectacles (10).
