一种自聚焦透镜的成像解

Imaging principle of a selffocusing lens

  • 摘要: 自聚焦锥透镜与圆柱透镜相比较,有其特殊之处。柱透镜在近轴平行光入射时,光线的振幅、相位、周期保持不变,而锥透镜的三者均发生变化,而且求解锥透镜的光线方程也比圆柱透镜复杂得多。本文推导了一个锥透镜的光线方程。可据此设计经过锥透镜后的光源大小,这在微系统照明中非常有用。

     

    Abstract: Compared with selffocusing cylindrical lens, selffocusing cone lens has its unique features. When paraxial collimated beam goes through a cylindrical lens, its amplitude, phase and period remain the same, but for a conelens, all these parameters are changed. Compared with the light equation for cylindrical lens, the equation for conelens is much more complicated. The paper derived a light equation for conelens. With this equation, the light spot size behind conelens can be designed. It can find application in microillumination systems.
