Iterative technique for high-resolution phase distortion compensation in adaptive interferometers

High-resolution adaptive phase distortion suppression is experimentally demonstrated for laser interferometers using a liquid crystal television as a phase modulator and an optoelectronic feedback loop.

Description
Summary:High-resolution adaptive phase distortion suppression is experimentally 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 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. ©
