Abstract
We suggest hardware realization of the Newton iteration method in the problem of modal reconstruction and correction of angular segmented mirror aberrations by functionals of the extended source image. A special basis for the wave- front aberration function, which makes it possible to cut the problem dimension in half is proposed. We present results of numerical simulation for the six-segment mirror with account for measurement noises.
