The system efficiency is the fraction of the energy in the source c c:xT0Y
beam that exits the optical system. This value is determined by j2+&B9 (

The coupling efficiency is the fraction of energy radiated N'4*L=Ut
by the source that couples into the receiver. This is the q+<TD#xoL
product of the system and receiver efficiencies.

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. 5QlJX
耦合效率的计算有一个积分过程,还是比较复杂的.
