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要求,为了达到这些技术指标,不仅需要光学系统设计满足这些要求,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0.05mm的分辨率,满足光谱仪位置调节需求。偏转维可以实现4-3°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 indictors, the optical system and 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＂
