摘要 |
A photo-electric sensor comprised of a wafer of semiconductor material with a first plurality of photodetectors integral with its rear surface, its front surface being an electrode comprised of a transparent layer of electrically conductive material, has those detectors so spaced apart from each other that the total array can be sampled by a second plurality of charge coupled device multiplexers, each of which multiplexers has its input terminals spaced closer together than are the photodetectors. Each multiplexer input terminal is mechanically and electrically coupled to a photodetector through metallic leads and columns, such leads and columns being so configured as to preclude obtrusion of multiplexer structure into space outside the wafer's lateral extremities, which results in no "dead" space in a focal plane consisting of either one sensor or a plurality thereof abutting each other.
