非功能式光纤传感器设计基础（二）：调制方式及其理论分析方法

Modulation types and its theoretical analysis methods

讨论了三种强度外调制的基本形式，即透射式、反射式和光闸式。在纤端光场分布函数的基础上，建立了相应的理论分析方法，并推广到光纤束传感器。最后给出了二则分析实例。

in this lecture we have discussed the three kind fundmental extrinsicintensity modulating methods: i.e. transmission types, reflective types andoptical shutter types. On the bases of output optical field distribution functionformed by the optical fiber end, the theoretical analysis methods areestablished respectively, which is also useful for fiber-optic bundle sensors.Finaly, two analysis examples are given.
