摘要
在光纤出射光场分布模型基础上 ,引进了Huffman在图像分析中使用的梯度空间概念 ,考虑了粗糙表面局部的空间光散射梯度 ,建立了二维光纤粗糙表面反射接收模型 ,设计了二维光纤传感器 .实验中 ,用 3到 7的立铣标准样板作为二维粗糙度的检测对象 ,采用被检测表面各点的特性曲线顶点标准差 ,找出了与粗糙度数值的依赖关系 .实验结果表明 ,二维光纤粗糙度传感检测方法能够同时获得表征二维工件表面粗糙特性的相关参数 ,对于工件粗糙表面特性评价提供了较为充分的特征数据 .
From the optical fiber scattering light field distribution model a two_dimensional optical rough surface reflection_reception model was established,and a two_dimensional fiber optic sensor was designed with the partial space optical scattering gradation of the rough surface tauen into consideration by introducing the 'gradation space'concept used by Huffman for image analysis,during the experiments,vertical milling standard samples from 3 to 7 were used as checked objects for two_dimensional roughness,and data was obtained from the measured curve peaks of the checked surface ,to establish the relationship between average disaffection value of roughness and standard deviation.
