Design of an optical system, whether classic or novel, in the past or the present, requires significant effort from the designer. In addition to design methods and theories, the designer's skills and experience in optical system design are particularly important, which may require years of practice to learn. The diversity and variety of results are limited because of the difficulty, time, and labor costs required. In this article, we propose an automatic design method for freeform optics that can achieve a diverse range of three-mirror designs. The optical specifications and the design constraints are the only inputs required, and a variety of results can be obtained automatically. The output results have various structures and various optical power distributions with high imaging qualities. By implementing the design method, designers can not only realize an overview of the solution space of the three-mirror freeform system, but can also focus on specific designs.
光学系统的设计，无论是经典的还是新颖的，无论是过去还是现在，都需要设计者付出巨大努力。除了设计方法和理论，设计者在光学系统设计方面的技能和经验尤为重要，这可能需要数年的实践来学习。由于所需的难度、时间和劳动力成本，结果的多样性和种类受到限制。在本文中，我们提出了一种用于自由曲面光学器件的自动设计方法，该方法可以实现多种三镜设计。光学规格和设计约束是唯一需要的输入，并且可以自动获得各种结果。输出结果具有各种结构和各种光焦度分布，成像质量高。通过实施该设计方法，设计者不仅可以了解三镜自由曲面系统解空间的概况，还可以专注于特定设计。
