The system efficiency is the fraction of the energy in the source G j[`r
beam that exits the optical system. This value is determined by j_\ns M7
the input na, entrance pupil size and position, apodization, #;59THdtPk
transmission of the optics, and vignetting. rcUXYJCh-

The receiver efficiency is the fraction of the transmitted energy jEwfa_Q%
that couples from the exit pupil to the receiving fiber. This ]]~tFdh
value is determined by aberrations and the na of the receiving fiber. fG2hCP+

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. Ig9yd S-.
耦合效率的计算有一个积分过程,还是比较复杂的.
