摘 要:成像光学系统的观测场景愈发复杂,为了实现物方到像方复杂的投影映射,传统的光学设计方法需优化控制不同视场的像高,该方法采样追迹计算量大。文中提出采用视场相关的局部参数作为优化控制目标,由局部焦距和局部F数实现复杂物像映射关系和分辨率的调控,并达到同步优化提升相对照度的效果。采用该方法分别成功设计了中央-20°~20°视场f-tanθ等线投影,边缘±20°~±60°视场f-θ等距投影,以及中央-16°~16°视场角分辨率相同、边缘±28°~±60°视场角分辨率相同且中央视场角分辨率为边缘视场角分辨率1.5倍/0.667倍的三款120°视场广角镜头。基于视场相关局部参数优化的光学设计方法展现了灵活的物像映射调控能力,对于光学系统在复杂类型观测场景中的应用具有非常重要的价值。Objective The goal of designing the imaging optical system is to image the object to be observed clearly to the image plane, and to realize the mapping relationship between object and image of the observation scene.According to the requirement of similarity between object and image, the pinhole imaging model is generally used, with rectilinear projection, which satisfies the f-tanθ mapping relationship. With the increase of the field of views(FOVs), an equidistant projection is produced, which satisfies the f-θ mapping relationship, and a variety of projections such as stereographic, equisolid, and orthographic are then derived. There are also more complex observation scenarios that generate more personalized mapping relationship requirements. As the scenes for imaging optical system is becoming more complex, the image heights for different FOV need to be carefully constrained when utilizing conventional design method to realize complex mapping relationship between object and image, which requires a large amount of calculations based on ray tracing. Therefore, it is necessary to propose a method that exhibits flexible constrain ability for mapping relationships and satisfies a lot of complex imaging scenes. For this purpose, an optical system design method for complex mapping relationship between object and image based on field-dependent parameters is proposed in this paper.Methods The essence of the mapping relationship between object and image is to describe the incremental change of image height with the change of the FOV. Due to the multi-type target scene observation requirements,the focusing ability and resolution of the optical system, complex requirements are put forward, and the local parameters related to the FOV can be more intuitive and accurate to characterize these requirements. If the full FOV is divided into multiple sub-fields, and the respective central reference is established in each sub-field of view, then each FOV has its focal length. Like the local focal length, the entrance pupil that c
