摘要

报道了一套适用于激光外差辐射计的高精度太阳跟踪仪, 为激光外差辐射计提供用以反演大气成分的柱浓度和垂直廓线的太阳光。 太阳跟踪系统采用太阳运行轨迹跟踪与光电跟踪相结合的跟踪方式, 具有精度高、 全时空特点。 测量了该太阳跟踪仪的跟踪精度, X和Y轴方向跟踪精度分别达到0.068°和0.06°, 能够满足激光外差辐射计在大气和天文领域中对太阳光收集的要求。 进而把太阳跟踪仪与实验室研制的激光外差辐射计集合起来, 测量了3.5 μm附近的太阳光谱, 得到了CH4在整层大气中的吸收情况, 为下一步反演整层大气中CH4的柱浓度和垂直廓线奠定了基础。

Abstract

This paper presented a high precision solar tracker for laser heterodyne radiometer with high resolution about MHz, which inversed a column concentration and vertical profile of the atmospheric composition. The solar tracking system using the sun tracking and tracking method had the characteristics of high precision, full time and space. This paper measured tracking precision of the sun tracker, and it’s X, Y axis tracking accuracy were 0.068° and 0.06°, respectively, which met the requirements of laser heterodyne radiometer in the atmosphere and in the field of astronomy. The system, combining the homemade sun tracker with laser heterodyne radiometer, obtained the absorption of CH4 in the atmosphere by solar spectrum around 3.5 μm, which laid the foundation for the inversion of the whole column concentration CH4 and the vertical profile of CH4 in the atmosphere.
