摘要
The disclosed position measuring device includes a position sensitive detector and a processing circuit therefor. The position sensitive detector includes two terminals carrying signals that vary oppositely according to the incident light. A switch connected to one terminal opens and closes the one terminal, and a signal processor processes one output of the position sensitive detector when the switch is opened and another output of the position sensitive detector when the switch is closed so as to produce normalized light/point position information. A control controls the signal processing circuit and the switch.
