The system efficiency is the fraction of the energy in the source vb3hDy
beam that exits the optical system. This value is determined by oj@=Cq':-
the input na, entrance pupil size and position, apodization, ,JfP$HJ
transmission of the optics, and vignetting. Q+s2S>U{v

The receiver efficiency is the fraction of the transmitted energy `x;m@\R
that couples from the exit pupil to the receiving fiber. This dnkHx
value is determined by aberrations and the na of the receiving fiber. k+~2

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. 2 a*+mw
耦合效率的计算有一个积分过程,还是比较复杂的.
