Abstract:The photoelectric conversion characteristic and detecting principle of the four-quadrant photo detector as position sensitive device are discussed in detail in theory applied to laser alignment. At the same time, the analyzing results are approved by the numerical simulation and experiment. The factors affecting the precision are analyzed detail by detail. The analysis results show that the theoretical basis for analyzing error during the laser alignment with four-quadrant detector.
Keywords:four-quadrant detector(4-Q detector)  laser alignment  position sensitive device  precision analysis
