The system efficiency is the fraction of the energy in the source 9MQ!5Zn
beam that exits the optical system. This value is determined by &~of]A

The receiver efficiency is the fraction of the transmitted energy dWbSrl
that couples from the exit pupil to the receiving fiber. This (_h<<`@B
value is determined by aberrations and the na of the receiving fiber. DPCB=2E

The coupling efficiency is the fraction of energy radiated #@s[!4)_I
by the source that couples into the receiver. This is the n1+1/

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. ZbVo<p5* ]
耦合效率的计算有一个积分过程,还是比较复杂的.
