反射式光纤束探头理论建模和仿真实现

摘要

Theoretical modeling of the optical fiber bundle probe was built by the analysis of light path and theoretical modeling of single fiber pair,and was simulated.Based on single mode fiber output of light and detection conditions of the intensity-modulated optical fiber sensor,the optical fiber bundle probe with one multimode fiber sending and six multimode fibers receiving was designed and implemented.The light source is divided into two ways by the optical fiber bundle probe,one is as the detection light path,and the other is as the reference light path.It achieves good results in the monitoring of the intensity-modulated optical fiber sensor.%在分析光路和单光纤对理论建模的基础上,建立了光纤束理论模型,并对模型进行了仿真分析.针对强度调制型光纤传感器光源单模尾纤输出以及检测条件,设计实现了一根多模光纤发送,6根多模光纤接收的反射式光纤束探头,光纤束探头把光源的光分成两路,一路作为检测光路,另一路作为参考光路,在强度调制型光纤传感器的测量中取得了良好的效果.
