| 在鱼眼镜头的设计过程中,设计者往往依赖设计经验选择专利作为初始结构,缺乏理论指导。在鱼眼镜头前光组结构和后光组的光焦度以及光学间隔的基础上,提出一种求解鱼眼镜头后光组曲率半径初始参数的方法。通过前、后光组球差和彗差的波像差平衡条件建立方程组,求解该方程组后得到后光组的各光学面曲率半径初值,并以曲率半径初值作为参考值,应用Zemax软件进一步优化,得到初始结构。研究表明,应用这种方法求解鱼眼镜头后光组的初始光学参数,能使优化算法在较短时间内搜索到最优的参数解。 |

| For lack of theoretical guidance in the design process of fisheye lens,people usually choose patents as initial structure based on the designers' experience.In this paper,we propose a method to solve the curvature radius of each optical surface of post-group optical system based on the initial structure of the pre-group and focal power and the optical interval of post-group system by solving the balance equation of spherical and coma wave aberration between pre-group and post-group.The curvature radius of each optical surface is solved.Furthermore,Zemax is utilized to optimize the results as a reference design to obtain an initial structure.The method to determine the optical parameters of post-group of the fisheye lens enable the optimization algorithm to obtain an optimized solution in a shorter time. |
