摘要
为了研制一种照度检测范围宽、结构简单、操作简便,并能产生均匀光辐射分布、自动调光的照度测量装置,通过对传统照度测试方法所使用的结构形式和光源进行分析,提出了一种采用曲面反光灯杯加内置灯的光源以及单片机自动控制的新型CCD摄像机照度检测装置的设计方法。并在文中详细介绍了光源设计、照度探测器设计、控制电路设计以及试验等研制过程,最终研制成功的新型CCD摄像机照度检测装置实现了光源的均匀辐射、自动调光等功能,适用于各类CCD摄像机1.0×10-1lx^1.0×105lx照度范围的检测。
To develop a convenient illumination detection device with a wide dynamic range,a simple configuration,an automatic light adjustment function and a uniform light radiation distribution,this paper presents a new illumination detection device for CCD camera based on analyzing the structure and light source used by the traditional illumination testing method.This new equipment uses a curved surface reflector lamp cup with an inner-fixed lamp light source,and it is automatically controlled by a single chip processor.We introduce the research work,such as the light source design,illumination detector design,control circuit design and experiment results.The new type illumination detection device for CCD camera realizes the functions such as uniform radiation and automatic light adjustment,its detection range is from 1.0×10-1 lx to 1.0×105 lx for diversified CCD camera.
