Abstract

A new signal processing circuit for position sensitive detector (PSD) is proposed in this paper. Using this circuit, the photocurrents of PSD can be directly transformed into digital signals, and the signal-to-noise ratio can be greatly improved, but the measurement time is extended. The measurement results show that the agreement between theory and experiment is quite good.
