The system efficiency is the fraction of the energy in the source ^JGwCHeb|H
beam that exits the optical system. This value is determined by 27MwZz
the input na, entrance pupil size and position, apodization, Xm<|m#
transmission of the optics, and vignetting. r x@2Dmt6

The receiver efficiency is the fraction of the transmitted energy UYzNaw4/x
that couples from the exit pupil to the receiving fiber. This BCX2C
value is determined by aberrations and the na of the receiving fiber. BadnL<cj]

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. -op)X>
耦合效率的计算有一个积分过程,还是比较复杂的.
