摘要
基于最优传输理论的光线映射方法,针对非对称的照明的光学系统设计需求,以光源到辐照面距离为20 mm,在范围50 mm×50 mm范围内实现字母"JL"为目标,计算了面向零扩展度光源自由曲面光学系统初始参数,在此基础上利用LightTools软件优化设计并仿真分析了面向零扩展度光源和扩展光源的自由曲面光学系统,结果表明:面向零扩展度光源时,自由曲面直径为86.52 mm,光源与自由曲面距离为34 mm,在辐照面上可以实现字母"JL"的照度分布调控;面向直径为10 mm的扩展光源时,自由曲面直径为435.16 mm,光源与自由曲面距离为242 mm时,在辐照面上可以实现字母"JL"的照度分布调控,说明所设计系统可以实现非对称照明分布调控,有效的提高了自由曲面光学系统的设计效率.
Abstract
Based on the light mapping method of optimal transmission theory,the initial parameters of the free-form op-tical system for zero extension light source are calculated for the design of the optical system for asymmetric illumina-tion,with the distance from the light source to the irradiated surface of 20 mm,and the realization of the letter"JL"within the range of 50 mm × 50 mm as the target.The initial parameters of the free-form optical system for zero exten-sion light source are calculated,and based on this,the free-form optical system for zero extension light source and ex-tended light source is optimally designed and simulated using LightTools software.The results show that for zero exten-sion light source,the free-form surface diameter is 86.52 mm,the distance between the light source and the free-form surface is 34 mm,and the illumination distribution control of the letter"JL"can be realized on the irradiated surface;when facing the extended light source with a diameter of 10mm,the diameter of the free surface is 435.16 mm,the distance between the light source and the free surface is 242 mm,and the illumination distribution control of the letter"JL"can be achieved on the irradiated surface,indicating that the designed system can realize the asymmetric illumi-nation distribution control and effectively improve the efficiency of the design of the free-form optical system.
