The system efficiency is the fraction of the energy in the source 24g\x Nnt
beam that exits the optical system. This value is determined by LL0Y$pHV
the input na, entrance pupil size and position, apodization, CI#6 r8u
transmission of the optics, and vignetting. TmS -w

The receiver efficiency is the fraction of the transmitted energy (yJY / |
that couples from the exit pupil to the receiving fiber. This ~cf*Oq
value is determined by aberrations and the na of the receiving fiber. 0I v(ioB=

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. w=QlQ\
耦合效率的计算有一个积分过程,还是比较复杂的.
