摘要

针对出射光场的光强分布是均匀分布和高斯分布两种情形，推导出了传感器输出量与位移之间的定量关系，建立了光纤位移传感器的理论模型，并对该模型进行了仿真分析。采用铁、铜、铝和镜面贴纸等材料制备反射面，通过实验验证了理论模型的有效性，为制作光纤传感器和实验教学提供理论依据。

Abstract:

For the two cases of uniform and Gaussian distributions of light intensity in the emitted light field，a quantitative relationship between the sensor output and displacement was derived．Subsequently，a theoretical model of the fiber optic displacement sensor was established，and this model was subjected to simulation and analysis．Ｒeflective surfaces were fabricated using materials such as iron，copper，aluminum，and mirror stickers．

Through experimental verification，the effectiveness of the theoretical model was validated． This research provides a theoretical foundation for the development of fiber optic sensors and for experimental teaching in

relevant academic fields．

Key words: fiber optic displacement sensor uniform distribution gaussian distribution displacement
