The system efficiency is the fraction of the energy in the source Obz Fh?W
beam that exits the optical system. This value is determined by ny 'wS
the input na, entrance pupil size and position, apodization, 2E$K='H:,
transmission of the optics, and vignetting. PHh4ZFl]_I

The receiver efficiency is the fraction of the transmitted energy dm~Uj
that couples from the exit pupil to the receiving fiber. This \jCN ]A<
value is determined by aberrations and the na of the receiving fiber. cGUsao

The coupling efficiency is the fraction of energy radiated C.(<IcSG
by the source that couples into the receiver. This is the {=Z _L?j
product of the system and receiver efficiencies. VTl\'>(Cl

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. ? \p,s-CR:
耦合效率的计算有一个积分过程,还是比较复杂的.
