低偏振系统在许多应用中具有重要的优点。由于具有七个自由设计参数，三镜反射系统具有实现低偏振的良好潜力。本文提出了一种低偏振共轴三反系统设计的一般方法。基于遗传算法，可以找到既具有较低偏振像差又具有较好波像差的同轴三反系统的初始构型，并在评价函数中加入了双衰减、延迟、波像差、结构尺寸、中间像面和平焦面等约束条件，使设计结果满足不同的要求。不同的评价函数产生不同的最优结果。本文提出的方法是通用的，可用于设计其他类型的光学系统，要求低偏振。
Low polarization systems have important advantages in many applications. Thanks to be with seven free design parameters, three-mirror reflective systems have good potential to achieve low polarization. A general method to design low polarization on-axis three-mirror systems is proposed in this paper. Based on genetic algorithms, the initial configurations of on-axis three-mirror systems with both low polarization aberrations and good wave aberrations can be found. In order to make the design results meet different requirements, various constraints are included in the merit functions, such as diattenuation, retardance, wave aberrations, structure size, intermediate image plane and flat focal plane. Different merit functions generate different optimal results. The method proposed in this paper is versatile and can be used to design other types of optical systems that demand low polarization.
