| 摘 要： | 一般干涉型光纤传感器的信号臂和参考臂臂长差较大,为增强混合效率,必须采用窄线宽激光器作为干涉光源,成本较为昂贵。而采用推挽式探头设计结构,由于两臂等长可以降低传感器对激光器线宽的要求,采用普通的激光光源就可以满足要求,拓展了系统的实用性。

| Abstract: | There are big length differences between signal fiber and reference fiber in usual interferometric optical fiber sensors.We should utilize narrow linewidth laser in order to enhance the mixing efficiency which costs much.The use of push-pull probe can lower the demand of laser linewidth in optical fiber sensors,so we can use normal laser in optical fiber sensors and spread practicability of the system.Based on the structure of push-pull probe,the influence of laser line-width on optical fiber sensors are an... |
