The system efficiency is the fraction of the energy in the source 6vVx>hFJ47
beam that exits the optical system. This value is determined by tBNkVh(c

The receiver efficiency is the fraction of the transmitted energy M@e&uz!Rx
that couples from the exit pupil to the receiving fiber. This CD\k.

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. ,nqG*

耦合效率的计算有一个积分过程,还是比较复杂的.
