A stereoscopic endoscope that includes at least one image sensor, one or more processing devices, and a display device. The image sensors sense a pair of stereo images, based on capturing light passing through apertures electronically defined at a first aperture location and a second aperture location, respectively, on a liquid crystal layer within the endoscope. The size of each aperture, spacing between the apertures, and polarization state associated with each aperture are controlled using corresponding control signals provided to the liquid crystal layer. The image data captured through the apertures is used to generate control signals representing one or more views of a surgical scene. The views are then presented on a display device.
