机械装置在研制和试验过程中,常常需要对移动机构的运动进行测量,以获得描述机构运动的位移、速度、加速度等实验数据。本文将介绍一种测量运动的非接触式光电方法。1.非接触测量技术当被测物体处在构件密集或无法靠近的位置时,其运动测量需要采用非接触技术。光电 During the development and testing of mechanical devices, it is often necessary to measure the movement of the moving mechanism to obtain experimental data such as displacement, velocity and acceleration describing the movement of the mechanism. This article describes a non-contact measurement of movement of optoelectronic methods. 1. Non-contact measurement technology When the measured object in the component-intensive or can not be close to the position, the motion measurement requires the use of non-contact technology. photoelectric
