The system efficiency is the fraction of the energy in the source (;6s)z
beam that exits the optical system. This value is determined by ZL%VOxYqi
the input na, entrance pupil size and position, apodization, ValS8V*N1
transmission of the optics, and vignetting. &v# `t~

The receiver efficiency is the fraction of the transmitted energy izt^Wi|
that couples from the exit pupil to the receiving fiber. This /jrY %C
value is determined by aberrations and the na of the receiving fiber. hWGZd~L

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. ` *9EKj
耦合效率的计算有一个积分过程,还是比较复杂的.
