本文应用阿贝成象理论建立了非功能型多模光纤传感系统模式噪声的数学模型,给出了模式噪声的数学表达式。实验与理论分析所得结果相一致。
In this paper, Abbe image theory is used to establish the mathematical model of mode noise in non-functional multi-mode fiber sensing system, and the mathematical expression of mode noise is given. The experimental and theoretical analysis of the results are consistent.
