Abstract

An adaptive system having 70, 400 wave-front control channels has been experimentally analyzed. Wave-front control is based on the diffractive-feedback principle and requires neither a reference wave nor direct wave-front measurements. The key system elements are a liquid-crystal television used as a phase modulator, a CCD camera, and an optoelectronic feedback loop. Experiments demonstrated efficient suppression of wave-front distortions belonging to a bandpass spectral domain. Results demonstrate the system’s potential as a secondary high-resolution adaptive feedback system for adaptive optics applications.
