The system efficiency is the fraction of the energy in the source &49u5&TiP
beam that exits the optical system. This value is determined by 3lo;^KX !
the input na, entrance pupil size and position, apodization, si_W:mLF{a
transmission of the optics, and vignetting. $4Z+F#mx

The receiver efficiency is the fraction of the transmitted energy R/^@cA
that couples from the exit pupil to the receiving fiber. This &4 ,WG
value is determined by aberrations and the na of the receiving fiber. Fi mN?s

The coupling efficiency is the fraction of energy radiated 9 5=g Y
by the source that couples into the receiver. This is the ! Eq#[Gs

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. sLb8*fak
耦合效率的计算有一个积分过程,还是比较复杂的.
