The system efficiency is the fraction of the energy in the source </fnbyGR
beam that exits the optical system. This value is determined by Yv{AoL~
the input na, entrance pupil size and position, apodization, ,UP6.C14
transmission of the optics, and vignetting. $6_J` 7

The receiver efficiency is the fraction of the transmitted energy ZE :oK
that couples from the exit pupil to the receiving fiber. This -{O2Nv- ]]
value is determined by aberrations and the na of the receiving fiber. dO=< 3W

The coupling efficiency is the fraction of energy radiated \nLO.,
by the source that couples into the receiver. This is the H=dj\Br`
product of the system and receiver efficiencies. B g3^BOT

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. x&;SLEM
耦合效率的计算有一个积分过程,还是比较复杂的.
