Abstract
A position sensing detector in which each of a plurality of sensing channels is provided with ends and an output current lead at each end of each channel. A light spot is imaged along the length of the channel. The channels are electrically isolated from each other. The channels may be proportional to a selected keystone pattern, and the channels may be rectangular-shaped and accommodate keystoning effects of an imaged beam.
