The system efficiency is the fraction of the energy in the source ybYXD?
beam that exits the optical system. This value is determined by sH@ &*
the input na, entrance pupil size and position, apodization, UzJ!Y / 5
transmission of the optics, and vignetting. JP%RTGu

The receiver efficiency is the fraction of the transmitted energy Xj;2h{#s
that couples from the exit pupil to the receiving fiber. This `skH-lk,
value is determined by aberrations and the na of the receiving fiber. `axQd%:AC

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. 2D_6
耦合效率的计算有一个积分过程,还是比较复杂的.
