The system efficiency is the fraction of the energy in the source S3EM6 `q'

The receiver efficiency is the fraction of the transmitted energy ;T6{J[

that couples from the exit pupil to the receiving fiber. This "|<6 bA
value is determined by aberrations and the na of the receiving fiber. A<-Prvryt

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. bV|(V >
耦合效率的计算有一个积分过程,还是比较复杂的.
