A Method and apparatus is provided for producing and displaying pairs of spectrally-multiplexed gray-scale or color images of 3-D scenery for use in stereoscopic viewing thereof. In one illustrative embodiment of the present invention, pairs of spectrally-multiplexed color images of 3-D scenery are produced using a camera system records left and right color perspective images thereof and optically processes the spectral components thereof. In another illustrative embodiment of the present invention, pairs of spectrally-multiplexed color images of 3-D imagery are produced within a computer-based system which generates left and right perspective images thereof using computer graphic processes, and processes the pixel data thereof using pixel-data processing methods of the present invention. Thereafter, produced pairs of spectrally-multiplexed images can be recorded on diverse recording mediums, and accessed by the display system of the present invention for real-time display on diverse display surfaces including, for example, flat-panel liquid-crystal display (LCD) surfaces, CRT display surfaces, projection display screen surfaces, and electro-luminescent panel display surfaces. In the various illustrative embodiments of the display system, stereoscopic viewing of 3-D imagery is facilitated by wearing electrically passive or electrically-active light polarizing spectacles during the image display process of the present invention.

A process for fabricating microchannel plates produces large area microchannel plates that have channel exit openings as small as 0.5 micron, MTF.about.1, pitch-limited resolution (a factor of 10 potential improvement in resolution) and at a cost of $0.40/sq. centimeter, and with funneling controlled as to configuration and exit opening size and shape. Microchannels may be rectangular in cross section, or rectangular, or trapezoidal, or other configuration, including straight sided, chevron or balloon sided. Microchannels of differing configurations may be interspersed, for reasons of alignment or to control pixel characteristics. Material choice may include glass, ceramic, metal, alloy and plastics, plus dopants. This materials flexibility, and the improved geometrical uniformity lead to higher signal-to-noise ratio and lower outgassing, and to a significant improvement in performance. Microchannels are formed in `green` glass/ceramic ribbons using high-precision, low-cost and versatile planar process steps, eliminating the need for the fiber-drawing and chemical-etching. The ribbon of green glass/ceramic powder in a binder and solvent slurry is configured in complementary partial microchannel forming grooves and partially dried to a safe handling condition, then carefully stacked upon a takeup device with precise alignment. The stack is cut into segments for final solidification by heat fusing and curing and sliced, then smoothed and equipped with appropriate ion barrier and electrode layers for use as microchannel plates.

An electro-optical display system for visually displaying a polarized spatially multiplexed image (SMI) of a 3-D object for use in stereoscopic viewing thereof with high image quality and resolution. In the illustrative embodiment, electro-optical display system comprises a liquid crystal display device and a micropolarization panel of electrically-passive construction. The liquid crystal display device has a display surface for visually displaying a composite pixel pattern representative of a spatially multiplexed image composed of first and second spatially modulated perspective images of the object, consisting of first and second pixel patterns. The micropolarization panel includes an optically transparent laminate portion and an optically transparent substrate portion which is in direct physical contact with the laminate portion. First and second optically transparent patterns are permanently formed in the optically transparent laminate portion. The first optically transparent pattern spatially corresponds to and is spatially aligned with the first pixel pattern displayed on the display surface so as to impart a first polarization state P.sub.1 to light emanating from the first pixel pattern and passing through the first optically transparent pattern. The second optically transparent pattern spatially corresponds to and is spatially aligned with the second pixel pattern displayed on the display surface so as to impart a second polarization state P.sub.2 to light emanating from the second pixel pattern and passing through the second optically transparent pattern.
摘要:
A desktop-based stereoscopic projection display system affording high-resolution stereoscopic and peripheral viewing of three-dimensional color imagery over a field of view of at least 180.degree.. The projection volume required by each image projector of the display system is disposed substantially within the overall display volume of the display system, while maximizing the viewing volume within which the viewer is free to move during interactive stereoscopic viewing sessions. The display system utilizes high-resolution image projectors, keystoning correcting optics and projection-beam folding mirrors which are compactly mounted immediately above the upper volume-boundary surface of the overall display volume of the system, in order to permit the use of three-dimensional display structures having footprints and display volumes that are supportable upon desktops and in other viewing environments characterized by spatial restrictions.

An apparatus for generating a three-dimensional image including two unmultiplexed images in stereoscopic relationship with each other. One of the images is of a material reflective of a given wavelength of left-handed (or right-handed) circularly polarized light, while the other of the images is of a material reflective of the given wavelength of right-handed (or left-handed) circularly polarized light. The materials include cholesteric liquid crystals.

A system for producing 3-D stereoscopic graphic hard copy output from computers is described. The left and right stereo images from the computer are spatially modulated, spatially multiplexed and then printed on a special paper. This special paper consists of a micropolarized sheet laminated to a polarization preserving reflective sheet. The spatially multiplexed stereo pair when printed on the micopolarizer and viewed with appropriatley polarized glasses, 3-D stereo images will result with full depth perception realized. The micropolarizer sheet seves as a spatial demultiplexer to separates the left and right images and codes them by means of two polarization states. The polarized spectacles serve as decoders and present to the left eye the left image and to the right eye the right image.

Miniature soft probes are used to provide a high speed connection to circuits on a wafer. The probe contains a co-planar line on a soft substrate which provides a flexibility for secure contacts. A miniature coaxial line is directly connected to the coplanar line with a zero degree angle. This configuration makes the probe very small and result in high performance. A planar link between two ground planes eliminates any unwanted odd mode. The probes have high speed and wideband transmission lines with interfaces which have speed in the picoseconds and bandwidths in the hundreds of gigahertz. The probes have multi-functional capabilities, such as high impedance buffering and DC blocking, due to printed circuits which constitute a portion of the probe. The printed circuits are produced by a thin film photolithic process. These probes are best suited for on-wafer tests, diagnostics and measurements as well as interfacing on-wafer circuits with other electronic or electro-optical systems.

The stack of N layers are sliced along a first and second line of the array of wells. The first line of the array of wells provides a first surface corresponding to a first array of channel openings of the MCP, and the second line of said array of wells provides a second surface corresponding to a second array of channel openings of the MCP. This method provides several functional benefits compared to conventional methods. These include, but are not limited to: the ability to produce well known and well characterized channels; the ability to produce well known and well characterized periods between channels; the ability to produce channels having any desired secondary electron emission enabling material therein; the ability to fabricate the substrate and/or final MCP of silicon.
