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 spectroscopy technology, and relates to a tracking instrument required for observing the sun and atmospheric ultraviolet spectra in the atmospheric stratosphere. Background technique: [0002] In the past two to thirty years, the international solar / atmospheric ultraviolet band spectroscopic observation research has been very active. In order to meet the needs of international development and domestic related 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 tracking. / Atmospheric ultraviolet spectroscopy ground observation, to obtain a lot of valuable data. In the early 1990s, the solar / atmospheric ultraviolet band spectrum high-altitude balloon observation experiment was launched, and a unique sun tracking device adapted to the ...
