Paper Abstract

We develop an algorithm of the wave front mode correction by the image in the adaptive optical system based on the Newton modified method. We show that the image control by the wave- front phase predistortions being checked makes the method invariant not only to the incoherent radiation source but in the first approximation to the wave amplitude forming the image. The consideration of the entire spatial spectrum of images in calculating the derivative matrix increases the method convergence. We present the results of numerical simulation of the segmented mirror phasing and alignment correction and the Zernike mode correction for a flexible mirror.
