Abstract

Target and environment are usually in bright or dark state in space. In order to overcome the shortage of traditional visible light camera which can’t obtain wide dynamic image, an ultra wide dynamic camera was designed in paper. On the basis of quantitative analysis of visible light scattering characteristics of target, the automatic exposure algorithm of area weight was proposed, and the stray optical light and high dynamic design of the camera were carried out to obtain more detailed information of target. Test results show that dynamic range of the camera was better than 100dB, and the actual value was 103.5dB. Meanwhile, the minimum sensitivity was 0.04Lux, and the minimum sun avoidance angle was 16° which could effectively eliminate stray light interference and meet the visible light imaging requirements of large dynamic space targets.
