摘要
为了实现太阳光谱辐照度的高精度观测,提出了视日运动轨迹和光电跟踪相结合的太阳自动跟踪方案,详细 论述了视日运动跟踪计算原理和基于四象限探测器的跟踪装置设计。为检测该装置的跟踪精度,设计 了基于线阵CCD探测器的跟踪精度检测系统,并开展了室外观测实验。测试结果表明,太阳跟踪精度 为±0.030°,稳定性优于1.4%,所设计的太阳跟踪装置在跟踪精度和稳定上均能够满足 太阳光谱辐照度观测的高精度跟踪要求。
Abstract
In order to achieve high-precision observations of solar spectral irradiance, a method which combines solar motion trajectory tracking and four-quadrant detector based on photoelectric tracking was adopted. The principles of solar motion trajectory tracking and the design of the tracking device based on four-quadrant detector were discussed in detail. To test the tracking precision of the device, a test system based on linear CCD was designed, and the outdoor experiment was carried out. The results show that the sun-tracking accuracy of the device is better than ±0.030, and the stability is better than 1.4%, which meet the requirements of the high precision spectral irradiance observation.
