摘要

自由曲面光学允许在成像和照明两个领域的整体系统设计。与透镜阵列相结合，它们可以实现先进的应用，如无像差成像和来自多个辐照源的光束再分配。本文介绍了一种切向和法向自由曲面光学阵列的自动化设计方法。优化线段的切向布局，增加了集光的立体角，从而提高了能效。然后利用基于费马原理和斯涅尔定律的迭代构造方法计算表面形状。复杂的照明与高达85%的光收集实验证明。

Optimization of segment topology and surface form for efficient illumination with freeform lens arrays

Freeform optics allow holistic system design in both fields of imaging and illumination. In combination with lens arrays, they enable advanced applications such as aberration free imaging and beam redistribution from multiple irradiation sources. This paper describes an automated design method for freeform optical arrays in both tangential and normal directions. Optimizing the tangential layout of segments increases the solid angle of light collection and thus improves energy efficiency. Surface shapes are then computed by an iterative construction method based on Fermat's principle and Snell's law. Complex illumination with up-to 85% light collection is demonstrated experimentally.
