Abstract

A stereoscopic endoscope comprises at least one image sensor for sensing a first image and a second image of a pair of stereo images. The first image is sensed based on light passing through a first aperture within the stereoscopic endoscope. The second image is sensed based on light passing through a second aperture within the stereoscopic endoscope. The stereoscopic endoscope further comprises a liquid crystal layer disposed between two layers of glass. The two layers of glass comprise a first arrangement of electrodes, such that each of the first aperture and the second aperture is created in the liquid crystal layer using a portion of the first arrangement of electrodes. A polarization state associated with each of the first and second apertures are controlled using corresponding control signals provided through the first arrangement of electrodes.
