Lateral effect position-sensitive detector is one of the detectors commonly used in laser trackers, particularly in out-door areas. In this study, we analyze behavior and simulation of this detector to different optical stimulators such as impulse, step and sinusoidal optical sources. For this purpose, typical parameters and equations are used in order to analyze the detector response to different optical stimulators. Finally, relative position of the incident light beam on the surface of the detector will be calculated with regards to the related photocurrents.
