V. P. Kandidov, O. A. Mitrofanov, V. V. Popov


Abstract: An algorithm for modal control of the phase of a light beam based on optimization of a multidimensional criterion is proposed and implemented experimentally. The components of this criterion are integral characteristics of the image of the beam in the observation plane. The algorithm performs adaptive focusing of the beam in a given region and the control is provided by the first five Zernike polynomials.
