Abstract:A system is developed for motion analysis by using position sensitive detector (PSD), as a transducer. It can detect positions of moving points accurately and give the loci in real time. The principle of the transducer, the composition of the detecting system and the technical key-points to improve the accuracy are presented. The experimental results of detecting the movement of points in 2D and 3D are shown in stick diagrams. This research was assessed in 1990.
Keywords:position sensitive detector  LED  optical filter  stick  diagram
