The system efficiency is the fraction of the energy in the source 'A@qg^e:`
beam that exits the optical system. This value is determined by A~6%,q@^jh
the input na, entrance pupil size and position, apodization, c y=I0
transmission of the optics, and vignetting. }b_R5U$@@

The receiver efficiency is the fraction of the transmitted energy aW0u8Dz
that couples from the exit pupil to the receiving fiber. This ,] ~u:Y}
value is determined by aberrations and the na of the receiving fiber. $i ,6B9

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. $Cz1C
耦合效率的计算有一个积分过程,还是比较复杂的.
