    摘要: The present invention relates to a light curtain that comprises at least one first optical unit having a plurality of light emitting elements and light receiving elements and at least one second optical unit having a plurality of light emitting elements and light receiving elements, wherein said light emitting elements and light receiving elements are operable to form a light grid from a plurality of light barriers formed between opposing light emitting elements and light receiving elements. The first and second optical unit each comprise a transceiver unit carrying said plurality of light emitting elements and light receiving elements, and at least one separate detachable plug-in module, said first and second transceiver units being identically built and said first and second plug-in modules differing from each other in order to define the functionality of the first optical unit and the second optical unit, respectively.

    摘要: The subject matter disclosed herein describes an optical sensor used in a safety system. The sensor includes two pixel matrices on a single substrate. Each of the pixel matrices are arranged in a row and column format, and pixels from one matrix are interspersed with pixels from the other matrix such that alternating pixels in each row and column belong to separate matrices. Two sets of selection logic allow each matrix to be enabled separately. Additional monitoring logic is included to detect shorted pixels and/or shorted selection lines. In addition, the frames generated by each pixel array may be compared to detect variation in performance between arrays.
