Abstract

The calculations have been carried to estimate the possibility of phase correction of the simplest Laguerre-Gauss vortex mode in an adaptive optical system without the wavefront sensor. The operation of bimorph adaptive mirrors with square and axisymmetric actuator packing under the control of the stochastic parallel gradient (SPG) algorithm has been simulated. As a result of SPG correction, the power fraction in the near-axis pinhole as well as the Strehl number increased to the level of 0.55-0.6 of the possible maximum.
