基于光电技术的速度测量方法

摘要

A velocity measurement method based on optical mouse and infra-red laser diode was described .With the infra-red laser diode and optical mouse navigation chip ,the device could detect the displacement of moving object .Time was measured by a single chip microcomputer ,thus a non-con-tact velocity measurement was realized .Furthermore ,the curve of the velocity and acceleration were also obtained .%根据光电鼠标成像定位原理，用红外激光二极管和光电鼠标导航芯片测量物体位移，用单片机定时器测量时间，计算得到物体运动的瞬时速率。该方法实现了对运动的物体进行非接触式测量，并可以获得物体的速度曲线和加速度曲线。
