    • PROBLEM TO BE SOLVED: To provide a method and apparatus for three dimensional video sampling or scanning with high precision and at a low cost.SOLUTION: A projector 20 projects a light beam that has been modulated by a digital micromirror device 22, typically contained within the projector. A modulation inserts information into the light beam that later allows depth information to be decoded. Specifically structural information is modulated into the light beam. A preferred embodiment uses a simple pattern of black and white stripes. The modulated beam is projected onto an object or scene and detected at high frame rate CMOS-based camera 24. A detected signal, summed from all pixels, is directed to a processor device 26, which extracts the depth information. The depth information is extracted from a way in which striping in an original signal has become distorted in reflection.

    • A night-vision instrument for presenting a 1:1 image comprises an objective, an image intensifier or converter tube, an ocular, a flat double-sided input mirror, and an optical system adapted to transfer the image appearing on the phosphor screen of the intensifier to the ocular. The ocular axis is in line with the viewed object, while the objective and the intensifier have their axis positioned at a right angle to the viewing axis. The input mirror is positioned in front of the ocular inclined at 45 DEG to its axis and to the axis of the objective, so as to direct the light rays received from the viewed object through the objective onto the cathode of the intensifier. The intensified image appearing on the phosphor screen is directed to the rear side of the input mirror by one single prism, one inclined mirror, one double prism and an optical lens system. The rear side of the input mirror projects the image through the ocular into the eye of the observer. The geometry of the instrument is such that the image of the object appears in the eye under the same visual angle as if viewed from the same distance by the unaided eye, which is obtained by making the distance between the optical center of the input mirror and the eye lens equal to the distance between the said mirror center and the optical center of the objective, and by designing the optical system accordingly.
