The system efficiency is the fraction of the energy in the source B @v H1T
beam that exits the optical system. This value is determined by *AQbXw]w
the input na, entrance pupil size and position, apodization, uBkn y;
transmission of the optics, and vignetting. OYp8r

The receiver efficiency is the fraction of the transmitted energy g uWqHVSs
that couples from the exit pupil to the receiving fiber. This $K fk=@
value is determined by aberrations and the na of the receiving fiber. Qu\l$/

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. K3D $

耦合效率的计算有一个积分过程,还是比较复杂的.
