The system efficiency is the fraction of the energy in the source +ai<

beam that exits the optical system. This value is determined by tX[WH\(xI
the input na, entrance pupil size and position, apodization, d_CT$
transmission of the optics, and vignetting. d 'ifLQ\

The receiver efficiency is the fraction of the transmitted energy &j6erwaT
that couples from the exit pupil to the receiving fiber. This w(F%^o\
value is determined by aberrations and the na of the receiving fiber. 1mJHued=6

The coupling efficiency is the fraction of energy radiated 3gzXbP,
by the source that couples into the receiver. This is the @]0%L0u

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. qP;OaM

耦合效率的计算有一个积分过程,还是比较复杂的.
