哈尔滨理工大学学士学位论文 照相镜头的研究进展

摘 要

对照相机来说,镜头是其最基本的元件之一,也是最重要的物理元件。纵观照相机的历史,镜头一直是相机的精髓所在,即使相机产业发展这么长时间,也依旧没有什么能用来取代相机的物理光学镜头。最近几年,随着现代照相镜头技术的发展,极大地促进了照相镜头技术的发展,而照相镜头技术也是现代光电子高科技产业的典型代表。

在对国内外照相镜头的发展现状进行了详细地介绍和分析之后,介绍了照相镜头的成像原理,阐述了镜头成像的像差分析方法以及像质评价方法,最后,详细地介绍了长焦连续变倍镜头设计的原理、系统初始结构的选择、并应用ZEMAX软件进行了镜头的优化、系统分析、并应用软件的光线特性曲线图、点列图、以及MTF图分析了该镜头的成像质量,最后得出了本论文的结论。并对今后照相镜头的发展提出了系统的改进方向。

关键词:照相机镜头;ZEMAX;像质评价

哈尔滨理工大学学士学位论文 Development of camera lens

Abstract

To camera, the lens is one of its most basic components, also the most important physical component. Throughout the history of the camera, the lens has been the essence place of camera, even if the camera industry develops so long time, it remain have no what can come to replace the physical optical lens of the camera. In recent years, the modern imaging technology grows so fast that it forms an industry, which is also a typical representation of the Hi-Tech optical and electronic. The research technique discusses how to design a consciously zooming lens unit with long focus, for details, there are how to carry out the optical and structural design of and how to ensure the design to achieve the requirements at the same article mainly. And apply ZEMAX software to carry on a lens of excellent turn, system analysis, and applied the ray characteristic curve diagram of software and ordered row diagram, and MTF diagram to hard analyze the lens of become be like quality, end get correspond of conclusion. And the last to the lens of the camera put forward a system improvement direction.

Keywords: camera lens; ZEMAX ; image quality evaluation
