摘要

设计了一种由GRIN透镜和菱形光闸反射体构成的光强度调制的垂直位移光纤传感器。对系统的输出光强与垂直位移之间的耦合关系进行了分析

给出了理论计算以及仿真

结果表明:两者之间存在着良好的线性区间

系统的量程和灵敏度直接与菱形光闸反射体结构大小有关。整个系统具有结构简单、动态范围宽、灵敏度可调、抗电磁干扰等特点。

Abstract

A new type of displacement sensor based on the principle of collimated beam reflective intensity modulation is presented

which is composed of graded-index（GRIN） lenses and some kind of reflective rhombic mirror.Artificial calculation shows that there is linear section between light intensity and vertical displacement

and the displacement sensor has wide flexibility in measurement range and sensitivity through adjusting the configuration parameters

with the advantage of simple structure and resisting electromagnetism.
