摘要
本文介绍了一种天空扫描系统，它以步进马达驱动机械部分的方位角传动轴和俯仰角传动轴，通过望远镜对天空半球扫描，所采集的天空辐射用导光纤维传输至三个颜色探测器，微机对三个探测器的光电信号快速采样，获得天空的亮度、色品坐标、色温等光参数。
A sky-scanner system is introduced in this paper, in the system the mechanical parts of the altitude angle and the azimuth are drived by two step-motors. A telescope is used to scan the hemispherical sky. The radiation from the sky is collected and transmitted through a optical fiber onto three color detectors. The signals from the detectors are sampled by computer, and the luminance, colour coordinates, color temperature of the sky can be obtained.
