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。
With the position sensor as a sensor developed into a good performance of the motion analysis system. It accurately locates multiple moving points and gives their trajectories in real time. In this paper, the working principle of the sensor, the structure of the test system and the technical key to improve the precision are introduced. The two-dimensional and three-dimensional experimental results of multi-point position are given in the form of stick figure. The result of this research was appraised in July 1990.
