    摘要: Apparatus for displaying an image suspended in space above a horizontal surface such as a tabletop or vehicle dash-board, of an original image below the surface, comprises a beam-splitter window in the surface and a retroreflector below the surface in a path for light reflected by the beamsplitter. The original image may for example be a VDU screen or vehicle instrument panel.

    摘要: A method of assaying for a ligand in a sample involves incubating the sample in contact with a specific binding partner for the ligand carried on one surface of an optical structure, irradiating the structure at a suitable angle or range of angles to the normal such that the resonance and/or total internal reflection of the radiation occurs within the optical structure and/or the layer of specific binding partner, and analyzing the radiation in order to determine whether, and if desired the extent to which and/or rate at which the generated radiation and/or optical characteristics of the optical structure are altered by complex formation.

    摘要: A border for a substantially two-dimensional image comprises an anterior pattern and a posterior pattern, the patterns being space one from the other and being arranged to form, when viewed together, a resultant apparent pattern in a different plane to that of the image. The patterns each comprise relatively brighter and relatively darker regions, but each usually has a different pitch. The posterior pattern may advantageously comprise an array of reflective dots printed onto a major surface of a light transmissive sheet which may be edge lit by a light source. The border brightness can then be independent of ambient light conditions and simple to manufacture.

    摘要: A liquid crystal display comprises a liquid crystal material layer contained between transparent slides which carry electrodes arranged in lines and columns to form an x, y matrix with x, y intersections. The liquid crystal layer at the intersections are turned on line by line by a blanking voltage, turned off by application of a zero voltage, and held at a threshold voltage at other times. The voltages are applied from a three phase supply by applying one phase to x electrodes a second phase to the y electrodes to maintain a threshold voltage at x, y intersections, and applying the third phase to both x, y electrodes for turning an intersection off. Alternatively the voltages may be applied from a two different frequency waveform supply.

    摘要: An imaging system for the generation of an apparent three-dimensional (3-D) image suspended in space for direct vieiwing includes a beamsplitter and a retroreflector. The optical property of reflecting light back along its original path enable the system to generate such an apparent 3-D image based on the perception of depth cues present in the original scene for viewing.

    摘要: A liquid crystal display comprises a liquid crystal material layer contained between transparent slides which carry electrodes arranged in lines and columns to form an x, y matrix with x, y intersections. The liquid crystal layer at the intersections are turned on line by line by a blanking voltage, turned off by application of a zero voltage, and held at a threshold voltage at other times. The voltages are applied from a two phase supply in the form of two sinusoidal waves spaced 60.degree. apart in phase. Threshold voltages at an intersection are maintained by applying one of the two waveforms to x electrodes and a zero voltage to y electrodes. A zero voltage at x, y intersections is arranged by applying the other of the two waveforms to both x, y electrodes.
