摘要： Embodiments of the invention relate to a spatial stereoscopic display device and an operating method thereof. The spatial stereoscopic display device comprises a laser source, a two-dimensional scanning unit, a variable isoclinic transflective unit, a power source and position sensor unit, an imaging space and a 3D modulator, wherein the two-dimensional scanning unit receives laser light emitted by the laser source and projects the laser light onto the variable isoclinic transflective unit according to specific addressing information under the control of the 3D modulator; the variable isoclinic transflective unit divides the laser light projected thereon into a first splitting light and a second splitting light intersecting in the imaging space, by transmission and reflection; the power source and position sensor unit is connected with the variable isoclinic transflective unit to control an intersection of the first splitting light and the second splitting light; the imaging space is provided with an up-conversion material, and the up-conversion material at the intersection of the first splitting light and the second splitting light is excited to form a light-emitting point; and the 3D modulator is connected with the laser source, the two-dimensional scanning unit and the power source and position sensor unit.

摘要： A stereoscopic display apparatus includes a source of illumination for emitting light, an imaging system for imaging the source of illumination at a viewing region, a spatial light modulator for modulating light from the source of illumination with two-dimensional images, and a control unit for controlling a relative position of the "active" source of illumination related to the imaging system. The stereoscopic display apparatus further includes a controller to vary the relative position of the "active" source of illumination in three directions which are orthogonal to each other, without physically moving a light source for inducing the source of illumination to emit light.

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 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.

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.
摘要翻译：通过逐像素地改变来自观看者的图像的表观距离，从二维显示获得三维图像。这可以通过将像素级光学元件的阵列与图像中的像素对准来实现。在优选的格式中，每个光学元件通常是细长的并且具有沿着其长度变化的焦距，结果是沿着其进入光学元件的长度的点确定相关联的像素的视觉距离观众。在阴极射线管应用的情况下，通过控制电子束在水平扫描时垂直移动微小距离来控制光的入射位置。在电视应用中，垂直距离可以由并入由电视机接收的广播信号中的深度分量来确定。还描述了与计算机监视器，电影和静止打印图像有关的应用和实施例。具体地说，提供了一种将3-D信息改造成常规2-D成像的方法，包括对场景进行数字化，定义场景中的各个物体的步骤，为场景中的每个物体分配指定深度的步骤，扫描场景中的每个像素并根据指定的深度将各个深度分量分配给像素。

摘要： Three-dimensional imagery based on a series of two-dimensional images is produced and displayed. A frame (20) housing a series of image displays (22) displaced at differing radial distances from the center (39) of the frame is rotated at 60 hertz or greater. As each display rotates past the viewer, a different sectional slice of a three-dimensional image is displayed. Thus, a full rotation of the frame provides the viewer with a full view of the three-dimensional object. The high rotational speed of the system visually merges the slices and the radial displacement of the displays provides depth to the image. This combination results in the presentation of a true three-dimensional image without the need for viewing aids. Additionally, multiple viewers can view the same or differing three-dimensional images.
