The receiver efficiency is the fraction of the transmitted energy 2+*o^`%4P
that couples from the exit pupil to the receiving fiber. This vN~joQ=d
value is determined by aberrations and the na of the receiving fiber. j9-.bGtm?.

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. ^g.H JQ'vF
耦合效率的计算有一个积分过程,还是比较复杂的.
