In this paper, the principle and the positioning error of the four quadrant photoelectric detector system are analyzed, and a new method for correcting the errors and correcting the non-uniformity of the four quadrant is presented. The relationship between the angular offset of incident light and the output voltage is deduced, and which is validated by experiment and calculation. In order to improve the detection accuracy of the four quadrant detector and eliminate the influence of various errors, a method is provided.
