The system efficiency is the fraction of the energy in the source k_y@vW3
beam that exits the optical system. This value is determined by }"3L>%Q5
the input na, entrance pupil size and position, apodization, }K&K{ 9}

The receiver efficiency is the fraction of the transmitted energy k:d'aP3
that couples from the exit pupil to the receiving fiber. This ;vd%=vR
value is determined by aberrations and the na of the receiving fiber. =fRP9`y

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. q4U?}=PD
耦合效率的计算有一个积分过程,还是比较复杂的.
