The system efficiency is the fraction of the energy in the source J\y^T3Z
beam that exits the optical system. This value is determined by ^2~ZOP $A
the input na, entrance pupil size and position, apodization, #<xFO^TB
transmission of the optics, and vignetting. .;4N:*hY

The receiver efficiency is the fraction of the transmitted energy ,{PN6B
that couples from the exit pupil to the receiving fiber. This O2Qmz=%
value is determined by aberrations and the na of the receiving fiber. p(n0(}eVC'

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. :^]Po$fl
耦合效率的计算有一个积分过程,还是比较复杂的.
