The system efficiency is the fraction of the energy in the source M?97F!\U
beam that exits the optical system. This value is determined by :oQaN[3>_
the input na, entrance pupil size and position, apodization, bZJiubBRI
transmission of the optics, and vignetting. 5$w1[}UUd

The receiver efficiency is the fraction of the transmitted energy $S/ 8T
that couples from the exit pupil to the receiving fiber. This BC+qeocg
value is determined by aberrations and the na of the receiving fiber. IS~oyFS

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. <z PyID`
耦合效率的计算有一个积分过程,还是比较复杂的.
