Development of High Precision Sun Tracker for the Application in Laser Heterodyne Radiometer
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.
