摘要
介绍了制作光纤迈克耳孙干涉仪的方法.光纤迈克耳孙干涉仪要用单模光纤传输光束,还要用可见光及不可见光调整光路,因此调试仪器比较困难.为了改善光斑的大小,需要安装自聚焦透镜,这样光斑直径就由原来的60μm扩大到1800μm.而干涉仪的调试可以通过近距离及远距离的方法实现,有时会出现信号波动大无法得到稳定读数的情况,这是反射镜M放置在特殊位置所致,文中对此做了详细介绍并给出了解决方案.
In this paper, a method for fabricating fiber Michelson interferometer has been presented. The interferometer guides light in single mode fiber and uses both visible light and invisible light to tune the optical link, which causes troubles when modifying the equipment. The self-focused tens is adopted to improve the size of light spot, making the diameter of light spot change from initial 60/~m to 1800/~m. As the modification of the interferometer can be a- chieved by short-distance and long-distance methods, sometimes the signal fluctuates so sharply that we can＇t obtain stable displayed data. The reason of this is that the reflector M was placed at particular position. The problem has been interpreted in detail and a solution has been proposed in this paper.
