Positioning Theories Of PSD And Application Research In Fuse

In this thesis, the positioning theories and applied technology of Position Sensitive Detector(PSD) are studied and summarized based on a large number of references. And the complete theory structure of PSD is set up. The paper got a conclusion that the position of facula determined by the amplitude method is just the centroid of light spot via the research of the amplitude method. The paper analyzed the facts which influenced the measuring precision of PSD and studied the methods which eliminated the noise of background. The paper brought forward a new principle application scheme of fuse based on PSD, especially gave a analyze and research of simulation on the approach of target identify and method of burst control. The paper also studied the method in measuring the burst point and tracking ballistic trajectory.
