Double-swing-arm scanning angle mirrors assembly of spaceborne Michelson interferometer has many technical difficulties, such as space cantilever structure with many dimensions, high precision and difficult detection, etc. This paper proposes a method of "vector analysis + precision micro-adjustment", and the following measures are taken: 1) Establish the assembly and inspection benchmarks; 2) Simplify the installation structure model of the angle mirrors assembly, simplifying the vertex of the angle mirrors into a space point vector, converting the adjustment of the space point into the in-plane adjustment and the normal adjustment of the installation surface according to the constraint conditions of installation and adjustment, and quantifying the adjustment amount by calculating; 3) According to the vector relationship of each adjustment quantity, the adjustment sequence of "first method to back plane" is designed; 4) According to the adjustment precision and the constraint state of the angle mirrors, special precision micro-motion device and other control measures are designed, and finally the high-precision adjustment of the spatial multi-degree-of-freedom angle mirrors assembly is realized. After the adjustment, the symmetry of the vertex position of the angle mirrors reaches 0.008mm, which is better than the design precision index. The interferometer has been successfully applied to Fengyun Meteorological Satellite, which has certain significance for the development of greenhouse gas space detection technology in China.
