摘要： A viewing device for viewing a relatively inaccessible gap between two closely positioned surfaces, such as a circuit component and a circuit board, may be viewed by a device including a first reflector which reflects light from the gap to a relatively accessible location for viewing. The first reflector is connected to a support which can be a bar or platform. Additionally a second element such as a second reflector or a threaded post can be included. Where the viewing device includes a first and second reflector connected by a platform support, the support may include a pair of threaded post holes on either side of a scored region. The support may be broken along the scored region to form two separate devices. The reflectors can be right angle prisms and may reflect light by total internal reflection or by a reflective coating.

摘要： A display system includes a relatively higher resolution display for presenting visual information, and a relatively lower resolution display for presenting visual information, the displays being positioned to present the visual information images therefrom in substantially side-by-side relation, the lower resolution image being provided by the cooperation of focusing optics which form a real image at a retro-reflector, which reflects light along an optical path conjugate with light incident thereon to provide an image for viewing, and the higher resolution image being provided without passing through the focusing optics. A method of display includes forming a relatively lower resolution real image, reflecting the image to the eye of an observer, forming a relatively higher resolution image, and directing the relatively higher resolution image to the eye of the observer such that at least a portion of the relatively lower resolution image circumscribes at least a portion of the relatively higher resolution image.

摘要： An electro-optical dithering system based on birefringence or double refraction increases the resolution of a display and includes a birefringent material, such as a calcite material, which selectively refracts or deflects light depending on an optical polarization characteristic of the light, and a switch to switch the optical polarization characteristic of the light, thereby to determine the location of output optical information. Thus, the apparatus and method of the invention can change the location of an optical signal, and the change can be used for a number of purposes, such as to improve resolution of a display, to provide an auto-stereoscopic output, to interlace optical signals, to facilitate locating and hiding of circuitry, to facilitate overlapping of tiles or pixels, etc.

摘要： A liquid crystal color display (20) provides a transmitted light output of one or more colors, black, and/or white, as a function of incident light and controlled energization or not of respective optically serially positioned liquid crystal color layers (2, 3, 4) and/or multicolor composite liquid crystal layer(s) in the display. Plural optically serially arranged volumes (21) of operationally nematic liquid crystal material (25) having different optical characteristics, e.g. being dyed with different pleochroic dyes (28), may be selectively aligned or not with respect to an electric field to determine optical output of the device in a subtractive color mode. Exemplary colors of pleochroic dye include yellow, cyan and magenta, and black dye may be used to control saturation or hue. Non-pleochroic dye also may be used in one or more layers of the liquid crystal color display to filter or to color light transmitted therethrough thereby to cooperate with the pleochroic dye to provide a final color output. Additionally, individual pixel-like areas (72, 73, 74) of the liquid crystal color display may be so positioned in proximity to each other to operate in a color additive mode. Techniques for discriminating voltage and/or frequency enable a multicolor response using only a single pair of electrodes. Using cross over liquid crystal material having positive and negative dielectric anisotropy characteristics as a function of frequency of applied signal, multiplex driving of the liquid crystal color display is facilitated.

摘要： A liquid crystal moving picture projector (1) includes a liquid crystal imager (2) for creating characteristics of an image, and projection optics (3) for projecting images sequentially created by the imager, the imager including a liquid crystal material (4) capable of temporarily storing information at respective areas thereof to create image characteristics capable of being projected sequentially by the projection optics. The temporary storage may be a function of charge storage directly on liquid crystal material or by structural storage characteristics relying on bulk effect of smectic liquid crystal. A method of projecting plural images in sequence includes creating an image or characteristics of an image in a liquid crystal material, storing such image in such liquid crystal material, directing light at such liquid crystal material, projecting such image as a function of light transmitted through or scattered by such liquid crystal material, and creating a further image in such liquid crystal material for subsequent projection.
