Abstract
A new experimental method is put forward for the influence of two laser spots on the direction deviation in four-quadrant photoelectric detection for laser guidance. The experimental apparatus and findings are given. The results are: in two cases of spot size, the curve of the relative center direction deviation vs. relative intensity difference of two laser spots; the deviation error in each quadrant under the condition of relative intensity difference value less than 2%. It is concluded that smaller relative intensity difference and larger spot size are beneficial to the decrease of the deviation error. Based on the experiments a new scheme of twelve -quadrant photoelectric detection to eliminate the influence of jamming spot on laser guidance is proposed: The twelve -quadrant photoelectric detector is composed of three four-quadrant photoelectric detectors arrayed in left, middle and right side. When a jamming spot appears, its relative position is judged by the circuit. When spots simultaneously appear in two quadrant photoelectric detectors, only the signal of target spot is put into succeeding control circuits, so the influence of jamming spot is eliminated.
