无人机载光学成像系统设计摘要如今社会信息的重要性逐步增强，而空间信息占着举足轻重的地位，但是常规卫星和航空遥感技术却有着许多的局限性，低空无人机（UAV）的出现为这些难题提供了解决办法，相比于常规卫星，无人机拍摄有很多优势，体积小、重量轻、可重复使用、成本低、便利。而且它的成像质量更高，分辨率更好。具有很好的发展前景。 本文设计了一焦距为 20mm，相对孔径 1：4，视场角 30°，分辨率 3μm 的无人机载光学成像系统，通过 zemax 对初始参数进行改变，使其达到设计要求，并且利用光学传递函数（MTF）进行优化，使其成像良好，最终进行像质评估和误差分析，得到一个合格的无人机载光学成像系统。关键词；无人机 光学成像系统 光学传递函数 像质评估AbstractNow the importance of the information society gradually strengthen, and spatial information occupy a pivotal position, but conventional satellite and aerial remote sensing technology has many limitations, the emergence of the low altitude UAV (UAV) provides a solution to these problems, compared with the conventional satellites, unmanned aerial vehicle (UAV) film have many advantages, small volume, light weight, reusable, low cost and convenience. It also has better imaging quality and resolution. Have very good development prospect.This paper designs a distance of 20 mm, relative aperture 1:4, the view Angle of 30 °, resolution 3 microns of unmanned aerial vehicle (uav) optical imaging system, using zemax to change of initial parameters, make it meet the design requirements, and using the optical transfer function (MTF) is optimized, make its good imaging, final image quality assessment and error analysis, get a qualified unmanned aerial vehicle (uav) optical imaging system.Key words; Image quality evaluation of optical transfer function of uav optical imaging system目录第一章引言........................................................................................................
