Abstract: The technology described herein can be embodied in a stereoscopic endoscope in which the orientation of the two eyes may be determined dynamically as the endoscope is moved and rotated. This may enable an improved user-experience when using an angled stereoscopic endoscope even when it is rotated, for example, to view the sides of a cavity.

Abstract: 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 one or more processing devices determine an orientation of a line connecting the first and second aperture locations relative to a reference orientation, and adjust at least one of the first and second aperture locations, while maintaining a spacing between them, in response to movement of the stereoscopic endoscope. 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.

Abstract: 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.

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.
