Illumination detection device for CCD camera

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 1.010-1lx to 1.0105lx for diversified CCD camera.
