The system efficiency is the fraction of the energy in the source top3o{ 4
beam that exits the optical system. This value is determined by .6e5w1r63
the input na, entrance pupil size and position, apodization, A' dt

The receiver efficiency is the fraction of the transmitted energy +SUQRDF@i
that couples from the exit pupil to the receiving fiber. This FjkE^o>
value is determined by aberrations and the na of the receiving fiber. +]5JXt^

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. *( D_g!a
耦合效率的计算有一个积分过程,还是比较复杂的.
