摘要: A visual communication system that is suitable for use in connection with a display surface is disclosed. The system includes a camera or other data-capturing device that can be remotely positioned from the display surface. A control unit receives image data from the camera or data-capturing device and processes the image data to create an electronic image of the display surface.

摘要: A beam sampler comprises a substrate made of highly transparent fused silica or zinc selenide, both capable of sustaining high power laser beams. The substrate defines an outer surface through which the light beam being sampled propagates. A sinusoidal diffracting relief is etched on this outer surface directly into the light-propagating material of the substrate. When a light beam propagates through the outer surface of the substrate, the three-dimensional diffracting relief extracts from this light beam at least one pair of low power beam samples.

摘要: A bireflective lens element comprising a light input surface and a direct transmitting area communicating with the light input surface. A light source is disposed adjacent to the light input surface for projecting light into the lens element to create a light emitting assembly. A first portion of input light is directed through the lens elements in a first predetermined pattern. A primary and a secondary reflecting area is between the light input surface and an illumination surface surrounding the direct light transmitting area. A second portion of input light is redirected through the lens element to the illumination surface in a second predetermined pattern. Specifically, the secondary reflective area has a plurality of extracting facets extending inwardly into the secondary reflective area for intercepting light from the primary reflective area. The first predetermined pattern combines with the second predetermined pattern to output light from the illumination surface in a substantially uniform pattern covering the broad area of the lens element.
