Abstract

The problem of optimization of the adaptive optical system using local curvature sensor is discussed. Computer simulations of the sensor including closed-loop operation are based on ray-tracing technique and numerical solution of Poisson equation by FEM method. Wavefront restoration for both axial symmetric and non-axial symmetric phase distortions is examined. It is shown, that choosing appropriate geometry of the actuator external electrodes one can improve wavefront restoration for the case of non- circularly symmetric Zernike aberrations.
