摘要

利用自制的光纤振动传感器和常规物理实验器材搭建了可用于多种物理量测量的实验装置。根据光纤振动传感器的动态特性，在其后坡线性工作区间内，采用共振法测量试验样品(锰钢条)的杨氏模量和物体的惯性质量。此方法测量精确度高、误差小、成本低、操作简单。

Abstract:

An experimental setup for measuring multiple physical quantities was constructed using a self-developed fiber-optic vibration sensor and conventional physics laboratory equipment．Leveraging the dynamic

characteristics of the fiber-optic sensor within its posterior slope linear working range，the resonance methodwas employed to measure the Young＇s modulus of a test sample (manganese steel strip)and the inertial mass

of objects． This approach offers high measurement precision，minimal error，low cost，and straightforwardoperation．

Key words: fiber optic vibration sensor reflective optical fiber Young＇s modulus inertial mass intensity modulation
