摘要

微透镜阵列在激光光束的扩展、塑形、均匀化和去相干性方面具有巨大的应用潜力。遗憾的是,微透镜目标散射角的增加会导致表面曲率增大。这会导致特定散射角范围内的透射率显著降低,直接影响光束整形和匀化过程。本文提出了一种大散射角随机微透镜阵列匀化光学元件的设计方法。采用透射和全内反射(TIR)相结合的方法,在保持高透射率的同时大幅增加微透镜阵列的散射角。利用随机边长比生成微透镜阵列的方法可消除干扰,提高光斑的均匀性。研究探讨了随机度改变过程中随机微透镜阵列的均匀性和能量利用率,并分析了加工误差对均匀化的影响。为验证新方法,开发了一种随机微透镜阵列,其散射角范围为 ± 41°,均匀度高达 82.31%,能量利用率为 85.48%。这项研究为开发大散射角随机微透镜阵列奠定了坚实的基础。

Design of random microlens arrays with large scattering angles
Microlens arrays exhibit significant potential for applications in laser beam expansion, shaping, homogenization, and decoherence. Unfortunately, an increase in the target scattering angle of the microlens results in higher surface curvature. This can lead to a significant reduction in transmittance over a specific scattering angle range, directly affecting beam shaping and homogenization processes. In this paper, a design method for randomized microlens array homogenizing optical element with large scattering angles is proposed. A combination of transmission and total internal reflection (TIR) is used to significantly increase the scattering angle of the microlens arrays while maintaining high transmittance. A method of generating microlens arrays using random edge-length ratios is used to eliminate interference and improve the uniformity of the spot. The study explores the uniformity and energy utilization of random microlens arrays during random degree alteration and analyzes the influence of machining errors on homogenization. To validate the novel method, a random microlens array has been developed, featuring a scattering angle range of ± 41°, remarkable uniformity at 82.31 %, and an energy utilization rate of 85.48 %. This research lays a solid foundation for developing random microlens arrays with large scattering angles.
