经过理论试算和实际处理表明，本方法能较好地消除球面发散和大地吸收对振幅的影响。
Theoretical and practical results indicate that the method can compensate quite desirably the amplitude attenuation due to spherical divergence and earth absorption.
只有发散球面波才是唯一稳定解。
针对将大发散角LED的光高效会聚到光纤接收端面的需求，提出了一种椭球面和聚光透镜组合光学系统设计的思路。
With large divergence Angle LED light efficiently converges at the optical fiber receiving end demand, an ellipsoid and focusing lens combination optical system design method is proposed.
