Abstract
In astronomy, there is a very important task - distortion correction. The problem is solved by an adaptive mirror with a variable geometry which can be created based on MEMS. The annex to the adaptive optics, MEMS is membrane mirror of small dimensions, but with a large number of controls. The action of external forces on the controls adjusts the mirror surface shape correction for distortion compensation. Force directed at one control element slightly affects the shape of the mirror surface in the areas where the remaining elements. It is shown that for each control of the mirror can be affected, which is proportional to the calculated value of the sensor by measuring the wavefront coming to the input aperture of the system.
