This paper introduces a kind of measuring system based on two-dimensional position sensitive detector PSD and single-chip signal processing, and have discussed the key technology. Two-dimensional position sensitive detector (2 D-PSD) is a kind of testing device of light spot position information and the output signal is a kind of current signal related to the location information. PSD output signal processing circuits are usually made by the I/V conversion circuit ,the addition, the subtraction and division arithmetic circuit. System can quickly, accurately and easily realize the position measurement, with a simple implementation, low power consumption, fast response, etc, It can be applied to many remote laser center positioning measurement and general industrial control occasions.

This paper presents Modeling and Simulation of Two-Dimensional Position Sensitive Detector (PSD) using MATLAB. PSD is an Optical Position Sensor (OPS) that can measure a position of a radiation spot in one or two-dimensions on a sensor surface. Unlike discrete elements such as Charge-Coupled Device (CCD), it provides continuous position data, features high position resolution and high-speed response which give this paper its importance. The sensor used consists of two-dimensional array of photodiodes. The sensor has four output photocurrents that change according to the position of incident radiation on the surface. The work is divided into three parts of Modeling and Simulation; the first part is a single photodiode, Second part is one-dimensional array of photodiodes and the third one is two-dimensional array of photodiodes. The tool used to do the simulation is MATLAB software because it is professional and accurate tool, it has photodiode element and it is possible to control the beam of incident light. This research can be useful for Acquisition; Pointing and Tracking (APT) systems where this sensor will give the necessary data to do tracking operation. Proteus software was also been used as a secondary tool.
