The system efficiency is the fraction of the energy in the source +|iYg/2
beam that exits the optical system. This value is determined by >EsziRm
the input na, entrance pupil size and position, apodization, i_Re*
transmission of the optics, and vignetting. hU]HTX'R

The receiver efficiency is the fraction of the transmitted energy M:KbD|
that couples from the exit pupil to the receiving fiber. This *l+OlQI0+
value is determined by aberrations and the na of the receiving fiber. $2^`Uca

The coupling efficiency is the fraction of energy radiated 2&PPz}Sw
by the source that couples into the receiver. This is the 51C2u)HE

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. vbx6I>\Y
耦合效率的计算有一个积分过程,还是比较复杂的.
