摘要
水陆两栖潜水车是未来汽车发展的方向之一,是汽车技术进一步向高端应用拓展的技术补充.针对水陆两栖潜水车对水下行驶过程超高清视频记录的需求,基于应用光学基本理论和Zemax光学设计软件,完成了以半球罩玻璃为视窗的小型水下定焦监控物镜设计,以适配微光监控相机.该系统光学总长度为58 mm,水下对角线视场角64°;当奈奎斯特频率为120 lp/mm时,系统的MTF均大于0.3,畸变为6%.该镜头结构简单紧凑,成像质量高,同样适用于其他水下运动平台.
Abstract
A amphibious underwater vehicle is one of the directions for the future development of automobiles and a technological supplement for the further development of automotive technology to high-end application.In or-der to meet the demand of amphibious underwater vehicles for the ultra-high definition video recording of their underwater driving,based on the basic theory of applied optics and Zemax optical design software,a small-sized underwater fixed-focus monitoring objective lens with hemispherical cover glass as the window is designed to adapt to a low-light monitoring camera.The total optical length of the system is 58mm,and its underwater diago-nal field of view is 64°.When Quineste frequency is 120lp/mm,the MTF of the system is greater than 0.3,and its distortion is 6%.This lens has a simple and compact structure and high imaging quality,and it is also suitable for other underwater motion platforms.
