一、前言为了适应高转速的需要,美国 NASA 刘易斯研究中心于1982年研制了一种数字式光学转矩仪(图1)。特点是在高转速下其性能有了改进,并且具有数据处理功能。它采用脉冲——时间检测的方法来测量扭焊的扭角。与以前的光学测扭方法不同的是:(1)对于轴与静止光学传感器之间的有限运动具有补偿功能。旋转部件与静止部件之间 I. Preface In order to meet the needs of high speed, the United States NASA Lewis Research Center in 1982 developed a digital optical torque meter (Figure 1). It features improved performance at high speeds and data processing. It uses the pulse-time detection method to measure the twisting twist welding. Unlike the previous optical twisting methods: (1) There is a compensation function for the limited movement between the axis and the stationary optical sensor. Between rotating part and stationary part
