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 and the second image is sensed based on light passing through a second aperture within the stereoscopic endoscope. The stereoscope endoscope comprises a liquid crystal layer disposed between two layers of glass comprising 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, wherein a spacing between the first aperture and the second aperture, and 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.
