title: Real-time compensation of phase distortions by digital phase conjugation using CCD and liquid crystal panel.
abstract: A video-rate optical phase conjugator using an image sensor and a liquid crystal panel that operated at 30 Hz was developed and its temporal characteristic was studied. Strong air turbulence of atmospheric structure constant, Cn=6.3×10(-7)  [m(-1/3)], was successfully compensated, reducing beam dancing by a factor of 2. To our knowledge, this is the first report demonstrating real-time wavefront correction by digital phase conjugation using commercial devices.
