The system efficiency is the fraction of the energy in the source Mo N/?VA
beam that exits the optical system. This value is determined by *s 4Ym
the input na, entrance pupil size and position, apodization, hR|x Up

The receiver efficiency is the fraction of the transmitted energy c]x-mj =
that couples from the exit pupil to the receiving fiber. This Z ;rM@x
value is determined by aberrations and the na of the receiving fiber. {0F/6GwUC

数值孔径不是越大越好呀,当耦合光学系统的模式与你光线的模式完全匹配时,耦合效率最大. >e/>@ J*
耦合效率的计算有一个积分过程,还是比较复杂的.
