摘要/Abstract

摘要：

差分吸收光谱仪具有114°×0.5°的视场、0.3-0.5 nm 的高光谱分辨率、13 km×48 km的高空间分辨率的技术指标，为了满足这些要求，不仅需要光学系统设计达到这些要求，也需要专门的平台用于装调光谱仪的光学系统。基于差分吸收光谱仪装调需求，研制了三维调整机构用于装调光谱仪的光学系统，三维机构分为升降维、偏转维和悬臂旋转维。升降维可以在竖直方向上下调节，且可达到0.05 mm的分辨率，满足光谱仪位置调节需求。偏转维可以实现±3°左右摆动，且可以实现3′的分辨率，满足光谱仪0.5°视场的需求。悬臂旋转维可以实现竖直面内±62°的旋转，通过两级蜗轮蜗杆运动传递实现5″的高分辨率，满足覆盖114°光源输入的调节。

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
