摘要： The invention is related to methods and devices for generating spatial images. The method comprises forming at least two directional radiation beams in a selected viewer's plane, each of the at least two directional radiation beams having a power from 0.05 to 10 of a human eye differential threshold for a current viewing condition, and directing at least two directional radiation beams to intersect and form a light spot at a crossover point, the light spot having an angular dimension corresponding to an angular resolution of a human eye and making the light spot visible from any point within the viewer's plane. Imaging is provided by means of a spatial displacement of a crossover point with an appropriate variation of brightness and/or color of said point, if required.

摘要： A video display for two or three dimensions has a flat liquid-crystal screen 2 which ejects light from the plane at a selectable line 3. One or, in the case of a 3-D display, several video projectors 1 project a linear image into the plane from an edge. A complete image is written on the screen by addressing the line with appropriate images as it is scanned down the screen. To screen a three-dimensional image the video projectors, each projecting an image as seen at a slightly different angle, combine to constitute a three-dimensional display which produces a three-dimensional image that is one line high.

摘要： A 3-dimensional image is obtained from a 2-dimensional display by varying the apparent distance of the image from the viewer on a pixel by pixel basis. This can be done by positioning an array of pixel-level optical elements in alignment with the pixels in the image. In a preferred format, each of the optical elements is generally elongate and has a focal length which varies along its length with the result that the point along its length at which light enters the optical element determines the apparent visual distance of the associated pixel from the viewer. In the case of a cathode-ray tube application, controlling the position of entry of the light is done by controlling the electron beam to move a minute distance vertically as it scans horizontally. In a television application, the vertical distance may be determined by a depth component incorporated in the broadcast signal received by a television set. Applications and embodiments relating to computer monitors, film and still printed imagery are also described. Specifically there is provided a method of retrofitting 3-D information to conventional 2-D imaging, comprising the step of digitizing each scene, defining individual objects in the scene, assigning a specified depth to each object in the scene, scanning each pixel in the scene and assigning respective depth components to the pixels according to the specified depth.

摘要： A system for displaying one or more images in three dimensions. The system has a three dimensional illumination volume containing a gas that emits one or more types of visible light when at certain multi-photon excited states. The system includes lasers (e.g. lasers with beams outside of the visible wavelengths) that can be directed to intersect in the illumination volume to excite particles of the gas to a multi-photon excited state to emit visible light. Scanning the beam intersection (or multiple beam intersections) through the illumination volume generates three dimensional images.

摘要： The invention relates to a night vision system for vehicles. According to the invention, the road in front of the vehicle is stereoscopically recorded via two night vision-capable cameras, e.g. infrared or low-light-level cameras that are mounted in the front of the vehicle at a distance from one another. Corresponding stereoscopic image display devices permit the driver to observe the road in front of the vehicle in three-dimensions. Objects located in front of the vehicle can be detected in critical areas by means of additional image evaluating devices and can be differently accentuated or marked in the image representation. The night vision system can be designed to also permit a two-dimensional display of images or data alternatively or in conjunction with 3D representation. In an enhanced embodiment, head movements and/or the line of sight of the driver are/is detected and used for a corresponding tracking of the image display.
