摘要
大孔径折反射成像系统被广泛应用于机器人导航和安全监控等领域。首先分析了超大视场光学系统六阶波像差理论应用于非球面光学系统的像差计算方法,随后基于该六阶波像差理论,构建了非球面大孔径折反射成像系统像差优化评价目标函数,并给出了求解这种包含多个光学参量的目标函数的优化算法,得到优化后的系统结构参数。最后,应用所提方法设计了一款工作波段为400~700 nm、最大视场角为120°、 F数为2.6且成像质量较好的光学系统。设计案例的结果表明所提出方法是有效的,为非球面大孔径折反射成像系统像差优化提供了一种有效手段。
Catadioptric imaging systems with large acceptance aperture are widely used in robot navigation and safety monitoring fields and so on.The sixth-order wave aberration theory of ultrawide-angle optical system applied to the aberration calculation method for aspherical optical system is analyzed firstly.Then,based on the sixth-order wave aberration theory,the aberration optimization evaluation objective function for aspherical catadioptric imaging system with large acceptance aperture is established,an optimization algorithm for solving the function consisting of multiple optical parameters is given,and the optimized structure parameters of the optical system are obtained.Finally,an optical system with wavelength ranging from 400 nm to 700 nm,maximum field of view angle of 120°,Fnumber of 2.6 and good imaging performance is designed using the proposed method.Results of the design case show that the proposed method is effective,which can provide an effective means for aberration optimization of catadioptric imaging systems with large acceptance aperture.
