摘　　要：文中主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、仪器结构简单、不会划伤被测件且能够显示被测件表面的具体形貌等优点。在测量中,我们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CCD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。This paper introduces a kind of real time measurement of part surface roughness using laser technique. In this measurement, triangulation measurement is adopted, by using non-diffraction laser beam as light source and high accuracy CCD pickup camera as displacement sensor. The surface roughness value is obtained by computer data processing and real time measurement of surface roughness becomes possible.
