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.

A system may comprise a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected; an occlusion mask device coupled to the projection device and configured to selectively block light traveling toward the eye from one or more positions opposite of the projection device from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and a zone plate diffraction patterning device interposed between the eye of the viewer and the projection device and configured to cause light from the projection device to pass through a diffraction pattern having a selectable geometry as it travels to the eye.

A system for performing stereoscopic views of digital photographs using a high resolution, retina display monitor, one or more lens stereoscopes positioned over a plurality of computer loaded images that has been pre-positioned and properly zoomed in for comparative purposes. A method for using the aforementioned system to perform 3D aerial photograph interpretations on digital only, rather than analog, images sent to the system and properly aligned/positioned on a high-resolution monitor using one or more positioned lens stereoscopes.

A light-deflection three-dimensional imaging device and a projection device, and the application thereof are provided. The light-deflection three-dimensional imaging device includes a projection device, a receiving device and a processor. The projection device includes a light source, a grating, a condensing lens group, a light deflection element and an emission lens, wherein after the modulation by the grating, the aggregation by the condensing lens group and the deflection by the light deflection element, the projection light transmitted by the light source penetrates the emission lens and is emitted from a side surface of the projection device. The light deflection element is provided to change a projection path of light emitted from the light source, thereby changing an installation manner of the projection device, so that the thickness thereof is significantly reduced, thereby facilitating the installation in lighter and thinner electronic mobile devices, such as a mobile phone, a laptop, a tablet computer, etc.

This marker comprises: a plurality of convex surfaces (121) that are formed of a translucent material and that are disposed at least along an X direction; and a plurality of to-be-detected parts which are disposed at front/rear positions with respect to the plurality of convex surfaces (121) and which are projected onto the plurality of convex surfaces (121) as optically detectable images. The plurality of to-be-detected parts are disposed so as to be positioned on the same virtual plane which is perpendicular to a Z direction of the marker. The virtual plane is positioned between a focal point (F) on an image plane (B) of the convex surface (121) in the Z direction and a high point (F) of the image plane.
