The system efficiency is the fraction of the energy in the source QnJLTBv
beam that exits the optical system. This value is determined by =te4p@
the input na, entrance pupil size and position, apodization, [ahwJ F#r
transmission of the optics, and vignetting. vQG v4

The receiver efficiency is the fraction of the transmitted energy Z^BZH/I?
that couples from the exit pupil to the receiving fiber. This ^ p7z3ng
value is determined by aberrations and the na of the receiving fiber. c_>AbF{

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. jo1z#!|Yw}
耦合效率的计算有一个积分过程,还是比较复杂的.
