| Abstract: | The meaning of Micromachine Membrane Deformable Mirror (MMDM) figure influence function is discussed, and the figure influence function matrix of oko company 37-channel MMDM is measured. The linear relationship between the deformation of mirror surface and single actuator voltages square is experimentally verified. MMDM correction capability is analyzed and a closed-loop correction model of adaptive optical system is established. An adaptive optical experimental system based on MMDM is built. Moreover, wave... |
