Computer simulation of the wavefront correction system with local curvature sensing

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 ofnon-circularly symmetric Zernike aberrations.
