Abstract

The aspheric surface is a commonly used method to improve the imaging quality of the fisheye lens, but it is difficult to determine the position and initial value. Based on the wave aberration theory of the plane-symmetric optical system, a method of using an aspheric surface to design a fisheye lens is proposed, which can quickly determine the appropriate aspheric surface to improve the imaging performance. First, the wave aberration of each optical surface of the fisheye lens is calculated and its aberration characteristics are analyzed. Then, a numerical evaluation function is reported based on the aberration distribution of the fisheye lens on the image plane. According to the functional relationship between the evaluation function and the aspheric coefficient, the position of the aspheric surface and the initial value of the aspheric coefficient can be calculated. Finally, the adaptive and normalized real-coded genetic algorithm is used as the evaluation function to optimize the fisheye lens using an aspheric surface. The proposed method can provide an effective solution for designing a fisheye lens using an aspheric surface.

确定鱼眼透镜设计中非球面的位置和初始值

非球面是改善鱼眼透镜成像质量的常用方法，但其位置和初始值很难确定。基于平面对称光学系统的波像差理论，提出了一种利用非球面设计鱼眼透镜的方法，可以快速确定合适的非球面，提高成像性能。首先，计算了鱼眼透镜各光学表面的波像差，并分析了其像差特性。然后，根据鱼眼透镜在像面上的像差分布，报告数值评估函数。根据评价函数和非球面系数之间的函数关系，可以计算出非球面的位置和非球面系数的初始值。最后，使用自适应归一化实编码遗传算法作为评价函数，对使用非球面的鱼眼透镜进行优化。所提出的方法可为使用非球面设计鱼眼透镜提供有效的解决方案。

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
