The system efficiency is the fraction of the energy in the source =r]_$r%gR
beam that exits the optical system. This value is determined by >^9j>< Z
the input na, entrance pupil size and position, apodization, K[noW
transmission of the optics, and vignetting. b4$. uLY

The receiver efficiency is the fraction of the transmitted energy ;MYK TE>m
that couples from the exit pupil to the receiving fiber. This gf9,/m
value is determined by aberrations and the na of the receiving fiber. ?P7QAolrr

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. 8_D:# i
耦合效率的计算有一个积分过程,还是比较复杂的.
