摘要
本文基于新导出的光纤出射光强的分布公式，给出了光纤接收光强的计算方法。该方法具有一定的通用性，可用于外部调制强度型光纤传感器调制机理分析及新型光纤传感器的设计。作为该计算方法的应用和验证，给出了反射型光纤位移传感器调制特性函数的解析表达式，其计算结果与实验相符。
This paper presents a way to calculate receiving light power in optical fiber based on a new formula for ligh intensity distribution of output light beam from optical fiber. It is of some commonality, and can be used in the modulation characteristics analysis of modulation intensity type fiber optic sensors and in the design of new type fiber optic sensors. As for its applications and verification, the analytical expressions for the modulation characteristics function of reflection type fiber optic displacement sensor are given, the calculation results agree with the experimental results.
