光纤表面粗糙度检测系统的研究

Research of Surface Roughness Detection System Based on Fiber

基于传光型光纤传感器,利用反射式光强调制原理,设计了一套材料表面粗糙度的检测系统。整个系统包含光源、Y型光纤束、反射调节控制装置和数据采集部分,采用单片机作为控制系统。分析了光纤束端面与检测样品距离的变化对检测结果的影响。

The design of a surface roughness detection system is based on light-transmitting fiber-optic sensor and the principle of reflecting and optical intensity modulating.The whole system,by single chip microcomputer as the control system,includes light source,Y-type liber bundle,rellection adjustment control device and data acquisition section.It analyzes thatthe change of distance between the liber bundle end lace and thetesting sam-ples has a marked impactontest results.
