The system efficiency is the fraction of the energy in the source g+ P
beam that exits the optical system. This value is determined by \2huDNW&

the input na, entrance pupil size and position, apodization, [zMnlO
transmission of the optics, and vignetting. (// f"c]/

The receiver efficiency is the fraction of the transmitted energy /lqVMlz\77
that couples from the exit pupil to the receiving fiber. This O[RivHCY

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. U,e'vS{
耦合效率的计算有一个积分过程,还是比较复杂的.
