Abstract:

The differential absorption spectrometer has the following technical indicators: the field of view 114°×0.5°, high spectral resolution 0.3-0.5 nm and high spatial resolution 13 km×48 km. In order to achieve the requirements, the optical system and the three-dimension mechanism are designed including elevating mechanism, swaying mechanism, and rotating mechanism. The elevating mechanism can be adjusted between ±150 mm with the resolution 0.05 mm in the vertical direction and meets the requirement for the position adjustment of the spectrometer. The swaying mechanism can sway between ±3°with the resolution 3′. The rotating mechanism can rotate between ±62° with the resolution 5″.

Key words: the assembly and debugging of the spectrometer, three-dimension adjustment mechanism, worm and gear
