Abstract

Heat source method was adopted to build a generalized mathematical model for the dynamic position detection of position sensitive detector. The impact of different scanning speeds on the position detection was analyzed. It is shown that the satisfaction of the linear relation between the detected positions and the true incident positions needs two conditions. The relative position detection error decreases with the decrease of the scanning speed or the increase of the angle intersected by the direction of speed and x-axis. The photocurrents for the analytical solution are compared with data simulated by the ANSYS software. Qualitative agreement is found.
