The system efficiency is the fraction of the energy in the source O67.DEu^
beam that exits the optical system. This value is determined by ^Pk-<b4}
the input na, entrance pupil size and position, apodization, E|jbbCZy2
transmission of the optics, and vignetting. P]4C/UDS-~

The receiver efficiency is the fraction of the transmitted energy OBCRZ
that couples from the exit pupil to the receiving fiber. This v~N8H+! d
value is determined by aberrations and the na of the receiving fiber. M#Vl{ b

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. /pvR-Id|6
耦合效率的计算有一个积分过程,还是比较复杂的.
