The system efficiency is the fraction of the energy in the source 1l^[%0
beam that exits the optical system. This value is determined by 4n(w{W>
the input na, entrance pupil size and position, apodization, jYAm}_?No
transmission of the optics, and vignetting. G){+.X4g3

The receiver efficiency is the fraction of the transmitted energy h'G
that couples from the exit pupil to the receiving fiber. This _f>)G3p
value is determined by aberrations and the na of the receiving fiber. RlvvO

The coupling efficiency is the fraction of energy radiated qycf;Kl:6
by the source that couples into the receiver. This is the C{l-l`:
product of the system and receiver efficiencies. ft{i6}

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. l&W:t9o
耦合效率的计算有一个积分过程,还是比较复杂的.
