Abstract

The limb UV radiation detection provides the information of atmosphere ultraviolet spectrum, so as to acquire the high resolution vertical distribution information of atmospheric trace gases and aerosol. Off-axis Three-mirror Anastigmat (TMA) system is adopted in limb UV radiation detection to increase horizontal space coverage. In this paper, opto- mechanical design of the system is introduced, and camera alignment is completed by computer aiding, then optical, mechanical and electrical combination as well as the optical performance test are carried out with the UV Image Intensifier. The camera’s wavefront error of each field is close to design value after alignment, the resolution reaches 140lp/mm in visible light band, and 20lp/mm in UV band, which reaches the design limit of the UV Image Intensifier, the optical system could well meet the operational requirement.
