Abstract
The applicability of wave-front correction by means of a bimorph mirro r in conjunction with a curvature sensor is described. We use Zernike polynomials to describe the quality of the atmospheric-turbulence corr ection analytically. The match is limited by boundary conditions of th e mirror and by the discreteness of the electrodes. The correction is limited by coupling of lower- and higher-order Zernike polynomials and necessitates an interfacing computer between the wave-front sensor an d the bimorph mirror.
