摘　　要：基于光的反射原理并结合光纤传感器的特点,设计了反射式光纤位移传感器应用设计性实验.利用反射式光纤传感器测量微小位移的原理,通过测量输出电压与位移的关系确定工作点,测得表面柤糙程度不同的真假钞的输出信号,从而实现对纸币的真假识别.Based on the law of optical reflection and the characteristics of fiber sensor, an application design experiment for reflection-type fiber displacement sensor was suggested. The sensor＇s working point was determined by measuring the relation between output voltage and displacement. False paper money with different roughness was identified by measuring the output signals.

关 键 词：光纤传感器 位移 粗糙度
