摘　　要：介绍了一种零件表面粗糙度的激光在线测量方法,该测量方法具有测量速度快且能够显示被测表面的具体形貌等优点.在测量中引入激光三角测量系统,用无衍射激光光束作光源,用高精度的摄像机作位移传感器,通过计算机数据处理得到表面粗糙度值,使表面粗糙度在线检测成为可能。A kind of real time measurement of part surface roughness using laser technique is introduced. In this measurement, we adopt triangulation measurement, use non-diffraction laser beam as light source and high accuracy pickup camera as displacement sensor. And the surface roughness value is obtained by computer data processing, real time measurement of surface roughness becomes possible.
