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.

过去或现在，光学系统的设计，无论是经典的还是新颖的，都需要设计者付出巨大的努力。除了设计方法和理论之外，设计师在光学系统设计中的技能和经验也特别重要，这可能需要多年的实践才能学习。由于所需的难度，时间和人工成本，结果的多样性和多样性受到限制。在本文中，我们提出了一种自由形式光学器件的自动设计方法，该方法可以实现多种多样的三反射镜设计。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。输出结果具有高成像质量的各种结构和各种光功率分布。通过实施设计方法，
