Abstract

Freeform optics have been extensively utilized in optical systems during the last few decades. Compared to their refractive counterparts, freeform reflective optics can yield larger angle of deflection, and more flexible geometry in three-dimensional space. Moreover, they are dispersion-free, and superior in thermal management. However, designing freeform reflective optics in highly tilted geometry is still not well addressed. In this paper, we propose a general formulation to design freeform off-axis reflective optics for precise illumination/intensity tailoring in highly tilted geometry. The superiority and effectiveness of the proposed method are verified by both numerical simulation and experimental results.

定制自由形态离轴反射光束整形系统

在过去的几十年里，自由曲面光学技术已被广泛应用于光学系统中。与折射光学器件相比，自由曲面反射光学器件的偏转角度更大，在三维空间中的几何形状更灵活。此外，它们不存在色散，在热管理方面也更胜一筹。然而，在高倾斜几何形状中设计自由曲面反射光学器件的问题仍然没有得到很好的解决。在本文中，我们提出了设计自由形态离轴反射光学器件的一般方法，以在高度倾斜的几何形状中实现精确的照明/强度定制。数值模拟和实验结果验证了所提方法的优越性和有效性。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
