Abstract

High resolution adaptive phase distortion suppression was experimentally demonstrated for laser interferometers using a liquid crystal television as a phase modulator and an opto-electronic feedback loop. The experiments were carried out for both amplitude division and rotational shear types of interferometers. The suggested iterative control algorithm is based solely on interference pattern information. The results of numerical simulations of a high resolution adaptive system based on rotational shear type interferometers show the system's potential for atmospheric turbulence phase distortion suppression.
