The system efficiency is the fraction of the energy in the source 'p80X^g
beam that exits the optical system. This value is determined by +^iUY%pm
the input na, entrance pupil size and position, apodization, l`UJHX
transmission of the optics, and vignetting. 4/&U s

The receiver efficiency is the fraction of the transmitted energy k"uqso/
that couples from the exit pupil to the receiving fiber. This y{0`+/\`
value is determined by aberrations and the na of the receiving fiber. ka0T|$ u(s

The coupling efficiency is the fraction of energy radiated rUvq AfE&+
by the source that couples into the receiver. This is the u -=S_e

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. sU^2I v\%
耦合效率的计算有一个积分过程,还是比较复杂的.
