The system efficiency is the fraction of the energy in the source z%:1)
beam that exits the optical system. This value is determined by [uR/M
the input na, entrance pupil size and position, apodization, AK2WN#u@Z

The receiver efficiency is the fraction of the transmitted energy CMl~=[foW
that couples from the exit pupil to the receiving fiber. This -MfQ&U
value is determined by aberrations and the na of the receiving fiber. FtIa*j^G

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. ~<ri97)
耦合效率的计算有一个积分过程,还是比较复杂的.
