摘要:
Apparatus for stereoscopically displaying radiographic images of the internal structure of an object and determining the spatial coordinates of a defect image inside the object, comprising: (a) two image display devices; (b) a secondary platform to support one of the two display devices with this platform being provided with horizontal movement means along with displacement sensor means; (c) a primary platform to support both image display devices; the primary platform being provided with movement means to horizontally slide both image display devices concurrently and the movement means being equipped with displacement-measuring means; (d) a sturdy base to support both platforms; (e) two reference lines being transversely aligned across and over the images; and (f) an observing assembly comprising two distinct and separate optical paths with each optical path being composed of properly arranged mirrors and lenses to direct the desired image into the respective observing eye. The optical paths are housed and protected by a casing means which is supported by a supporting member and provided with drive means to move the optical paths transversely; this supporting member being further supported by a sturdy base.
摘要:
Recent advances in surface techniques have lead to the development of extremely small (sub-micron) scale features. These techniques allow the formation of polymer micro-lenses as well as variable focus liquid lenses. The present invention primarily concerns the use of small scale lenses for the fabrication of novel displays which exhibit three-dimensional (3D) effects. Both still images and video images (or other motion images) can be generated.

This invention relates generally to new and improved approaches for displaying volumnetric three-dimensional (3D) images. The basic idea features new optical-mechanical mechanisms enabling creation of volumetric 3D images by successive projection of whole frames of 2D images. This new method projects a series of frames of 2D images, through an optical-mechanical image delivery system, onto a translucent screen which moves periodically and sweeps a space. As viewed from outside the space, the series of 2D images distributed in the space form a volumetric image because of the after-image effect of human eyes. Many viewers can walk around the space and see the image from omni-directions simultaneously without wearing any kind of glasses.

A passive dithering display system includes an optical display including a plurality of pixels with optical dead space between the pixels for producing an image, and a birefringent material for shifting one polarization component of the image relative to a second polarization component of the image such that the shifted polarization component lies in the dead space. Thus, the system of the invention can change the location of an optical signal, and the change can be used to improve resolution of a display, to reduce fixed pattern noise of a display, to facilitate locating and hiding of circuitry, to facilitate overlapping of tiles or pixels, etc.

A digitized video system having a processor and a video memory. The processor converts a stream of digital information to extract planes of a three dimensional image to store into the video memory to display a three dimensional image. A spatial light modulator is connected to the video memory to receive and display a plane of said image to display a three dimensional image.
摘要:
A multi-mode stereoscopic imaging system is described. It is the first stereo system which is convertible back and forth from the auto stereo viewing mode without glasses to the binocular stereo viewing mode with glasses. It is based on micro-polarizer arrays and spatial multiplexing of images. The system consists of a stereo image component and an auto parallax barrier component. Both components use the properties of .mu.Pols. Switching from one mode to the other is accomplished manually, and electronically with the aid of a liquid crystal light valve. The system combines the benefits of auto-stereo imaging and the binocular stereo imaging of prior art techniques without their limitations.

Three-dimensional image transmitting apparatus including camera means having a scanner for scanning a subject with a scan beam. Signal generator means is provided which includes a generator screen disposed in the path of the scan beam as reflected from the subject and such generator means is responsive to impingement of the scan beam on the generator screen to generate an electrical location signal corresponding with the location of impingement on the signal generator screen by the scan beam. Image reconstruction means is provided which includes a variable depth reconstruction screen that is rendered locally luminous in response to impingement by a trace beam. A trace beam source is provided for directing a trace beam at the variable depth screen in a pattern determined by the location signal. Variable depth screen control means is responsive to positioning of the scanner to render the variable depth screen operative at depths corresponding to the position of such scanner.
