摘要:本论文主要研究采用线阵CCD结合于柱面透镜成像特点和相关技术实现实时测量高速物体的三文位置坐标与速度。详细介绍柱面透镜成像特点及设计大视场的柱面透镜系统。对CCD的采集速度和灵敏度提出了几种提高方法。其中采用低通滤波器的输出作为判决电路的比较电压值是本人查阅了一些国外文献,已成功应用于其它领域的一种先进的做法,能使系统对复杂的背景光都能工作。另外CCD的串行,并行拼接也是一种中外常用来提高检测速度和精度也被本人采用来实现扩大检测范围和速度。本论文完成的基础是通过研究大量有关二文系统设计的参考资料及有关线阵CCD的基本知识。6962

Title Using CCD intersection optical target to measurement position and velocity of high-speed flying object
Abstract
This paper discuss using linear CCD array, cylindrical lens imaging characteristic and be related to it’s technology to measure position and velocity of high-speed flying object. Detail product cylindrical lens imaging characteristic and desire the big field of view lens system. Give out several method to increase the speed and sensitive of system device. In this paper I have used out put of low-pass filter as reference value of comparing circuit. By this method, the system will be effortless to work in complex of back light. Beside, using several linear CCD array in series or in parallel being a effortless and common use of method to increase the work speed and the precision was used in this paper. This paper was completed by reading very much due to 2-Dimension material and others.
Keywords: linear CCD array,locating,fling object,3-Dimension measuring,high-speed object.
