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=6.3×107[m1/3], 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.
