| 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. |
