The system efficiency is the fraction of the energy in the source U~e^
beam that exits the optical system. This value is determined by ,awp)@VG7
the input na, entrance pupil size and position, apodization, ^7l^ /GSO
transmission of the optics, and vignetting. 7>Oa, \

The receiver efficiency is the fraction of the transmitted energy .`ppp!:a4
that couples from the exit pupil to the receiving fiber. This 5%E.UjC
value is determined by aberrations and the na of the receiving fiber. `*n K@:

The coupling efficiency is the fraction of energy radiated w/(hEF '
by the source that couples into the receiver. This is the I3ZbHb-)_,
product of the system and receiver efficiencies. 4vk^=

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. -bHfo%"^TT
耦合效率的计算有一个积分过程,还是比较复杂的.
