The system efficiency is the fraction of the energy in the source :If1zB)
beam that exits the optical system. This value is determined by }J&[Uc
the input na, entrance pupil size and position, apodization, %rZJ#p[e)=
transmission of the optics, and vignetting. 6?v)Hb}J%d

The receiver efficiency is the fraction of the transmitted energy L z'05j3!
that couples from the exit pupil to the receiving fiber. This -Am ~CM
value is determined by aberrations and the na of the receiving fiber. I`e |[k2

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. #{8n< sE
耦合效率的计算有一个积分过程,还是比较复杂的.
