Abstract

Method of light-wave measurement for adaptive optical systems, which may be useful in conditions of the strong fluctuations, is considered. It is proposed to measure the light-wave phase on a closed trajectory, lying into the aperture where the wave intensity is significant, and to locate boundaries of the probably optical vortices, within which the intensity is close to zero. Operations and schematics of two novel devices are described, namely Hartmann Scanning Sensor and Directional Shearing Interferometer.
