Abstract
A novel optical detection apparatus is disclosed comprising a plurality of photodetectors and a plurality of transimpedance amplifiers wherein the photodetectors and the amplifiers are electrically connected to each other and are located in close proximity to each other, thus allowing the detecting of high frequency optical signals over a large detection area. Further, logical circuitry is disclosed for processing the signals generated from the photodetectors and for determining the strength of incoming light signals on various portions of the detection area.
