摘要
提出一种基于激光散射法的在线测量方法,以条形激光光束作为光源照射被测物表面,然后用配有高倍率镜头的工业相机采集散射光的图像,最后通过计算机数据处理得到表面粗糙度值。实验证明,该测量方法具有测量速度快、仪器结构简单、非接触且能直观显示被测工件的表面形貌等优点。
This paper present a kind of on-line measurement based on laser light scattering. In the measurement, the surface of workpiece is irradiated by laser beam as light source, then the scattered image is token by industry camera with high magnification lens. Lsatly, the value of roughness can be worked out by computer processing. The experimental results show this metod has several excellence as follows： rapidity, simple configuration, non-contact, display surface＇s figure on screen.
