摘要
用位置敏感器作为传感器研制成一种性能优良的运动分析系统。它可以精确地确定多个动点的位置并实时给出其轨迹。文中介绍了传感器的工作原理、测试系统的构成及改善精度的技术关键，并以棍图形式给出多点位置的二维、三维实验结果。此项研究成果已于１９９０年７月通过鉴定。
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.
