From the viewpoint of ensuring the imaging quality of scanning mirror
the principles followed in selecting material for scanning mirror and its supporting structure are described. The ways of supporting scanning mirror and their applicabilities are discussed. The design concept of flexure supporting structure is proposed for mirrors with higher profile accuracy requirements. The mirror assemblies both before and after the flexure supporting structure are analyzed under different working conditions using CAD/CAE engineering analysis software. The effectiveness of this flexure supporting structure can be substantiated through comparative analysis of finite element model deformation. The reliability of the mirror supporting structure is finally determined by the imaging quality of camera tested under field conditions.
