Abstract
High-resolution adaptive phase distortion suppression is ex- perimentally demonstrated for laser interferometers using a liquid crystal television as a phase modulator and an optoelectronic feedback loop. The experiments are carried out for both amplitude division (Mach- Zehnder) and rotational shear types of interferometers. The suggested iterative control algorithm is based solely on interference pattern infor- mation. The results of numerical simulations of a high-resolution adap- tive system based on rotational shear type interferometers show the sys- tem's potential for atmospheric turbulence phase distortion suppression.
