The system efficiency is the fraction of the energy in the source O2"V'(
beam that exits the optical system. This value is determined by ekqS=KfWl;
the input na, entrance pupil size and position, apodization, @Bn4ZF B@
transmission of the optics, and vignetting. KL$> j/qT

The receiver efficiency is the fraction of the transmitted energy 14*6+~38m&
that couples from the exit pupil to the receiving fiber. This [7 0 5[
value is determined by aberrations and the na of the receiving fiber. QS1lg

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. ai; Q,Vy
耦合效率的计算有一个积分过程,还是比较复杂的.
