Abstract
A phase compensation technique and apparatus utilizes a laser transmitter, acousto-optic/electro-optic modulators and a GRIN lens array to send out and receive phase shifted laser beams. Turbulence and optical phase distortions are compensated on outgoing and received wavefronts utilizing signal processing of the detected, mixed received and local oscillator beams.
