摘要
采用激光光杠杆放大的方法,利用位置敏感传感器(PSD)探测激光光点的位移,通过AD转换,由计算机EPP接口对数据进行采集,并利用C++开发了基于WINDOWS平台的数据采集处理可视化界面,设计实现了对悬臂梁微挠度的测量,最终得到薄膜磁致伸缩系数λ的可视化计算机辅助测试系统。
In this paper, the method of laser cantilever magnification was used for the measuring of the thin film magnetostrictive coefficient. The displacement of laser beam was detected by the Position Sensitive Detector(PSD). Through A/D transition, the data were collected by EPP port of the computer. Then the visual interface based on Windows platform was written in C^++ language. The cantilever micro-deflection measurement was designed and realized. The visual computer assistant measuring system of thin film magnetostrictive coefficient is realized successfully.
