Abstract—
Based on the numerical simulations in ANSYS software the design of a monomorph (unimorph) deformable mirror has been developed. The control electrodes pattern, which allows reproducing aberrations up to 5th order (the first 21 Zernike modes) on the light aperture with high fidelity, was chosen. All important characteristics of the monomorph mirror were simulated: electrode-influence functions, errors in the reproduction of given aberrations, gravitational sag of the mirror, mirror surface deformations due to ambient temperature changes, thermal deformations and thermal field due to the incident laser beam, and natural frequencies of the mirror. The results prove a high efficiency of this mirror as an element of adaptive optics systems.
