The system efficiency is the fraction of the energy in the source f%/6kz
beam that exits the optical system. This value is determined by 8K9RA<

The receiver efficiency is the fraction of the transmitted energy %x8vvcO^t
that couples from the exit pupil to the receiving fiber. This q\ /xx`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. cv_t2m
耦合效率的计算有一个积分过程,还是比较复杂的.
