Free-form lenticular optical elements and their application to condensers and headlamps
摘要：
Some embodiments provide an illumination optical system. The optical system can include a first surface and a second surface. Each of the first and second surfaces can further comprises a multiplicity of corresponding Cartesian-oval lenticulations such that each lenticulation of the first surface focuses a source upon a corresponding lenticulation of the second surface and each lenticulation of the second surface focuses a target upon a corresponding lenticulation of the first surface.
摘要（中）：

一些实施例提供照明光学系统。 光学系统可以包括第一表面和第二表面。 第一表面和第二表面中的每一个还可以包括多个对应的笛卡尔椭圆形微透镜，使得第一表面的每个微透镜将光源聚焦在第二表面的相应的微透镜上，并且第二表面的每个微透镜将目标物体聚焦在相应的 第一表面的光滑。
