Liquid crystal micromirror for wavefront addressing measurement and adjustment

The utility model discloses a liquid crystal micromirror for wavefront addressing measurement and adjustment. The liquid crystal display panel comprises a first antireflection film, a first substrate,a patterned electrode, a first liquid crystal orientation layer, a liquid crystal layer, a second liquid crystal orientation layer, a common electrode, a second substrate and a second antireflectionfilm which are sequentially arranged in parallel from top to bottom, the patterned electrode and the common electrode are concentrically arranged; the patterned electrode comprises a circular sub-electrode and a plurality of fan-shaped sub-electrodes which are concentrically arranged from inside to outside; the plurality of fan-shaped sub-electrodes on the same layer have the same central angle; and all the fan-shaped sub-electrodes on the same layer form a complete circle, and the circular sub-electrode with the number of (i, j) and all the fan-shaped sub-electrodes are led out from the patterned electrode through res
