The system efficiency is the fraction of the energy in the source vP z$jeA
beam that exits the optical system. This value is determined by 9%55R >s$
the input na, entrance pupil size and position, apodization, 3WZdP[o!
transmission of the optics, and vignetting. $$ma1.t"

The receiver efficiency is the fraction of the transmitted energy mxt fKPb
that couples from the exit pupil to the receiving fiber. This yAz`n[
value is determined by aberrations and the na of the receiving fiber. f_2tMiy 5

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. zg L0v5vk
耦合效率的计算有一个积分过程,还是比较复杂的.
