Abstract

This invention relates to one air stratosphere tracing device to observe sun and ether violet spectrum, which comprises pitching angle or direction angle drive structure, four-quadrant detector, electrical control system and spectrum eradiation meter. The bearing system in the invention adopts molybdenum disulfide solid lubrication to ensure the operation in temperature of -60Deg C. and several millimeter Hg in vacuum and adopts the pitching or direction angle drive structure and balloon hanging rope.

Description

Technical field: [0001] The invention belongs to the field of spectrum technology, and relates to a tracking instrument required for observing the sun and atmospheric ultraviolet spectrum in the atmospheric stratosphere. Background technique: [0002] In the past 20 to 30 years, the research on solar / atmospheric ultraviolet spectrum observation has been very active in the world. In order to meet the needs of international development and related domestic research, in the late 1980s, with the support of the 863-2 project, Changchun Institute of Optics and Mechanics developed a solar / atmospheric ultraviolet spectroradiometer and a matching ground tracking device and carried out long-term solar / Atmospheric ultraviolet spectrum ground observation, obtained a lot of valuable data. In the early 1990s, the high-altitude balloon observation experiment of the solar / atmospheric ultraviolet band spectrum was carried out, and a unique device for tracking the sun adapted to the high-al...
