Abstract: An atmospheric turbulence data optical LIDAR system for computation of wind velocity includes a laser (16) to transmit one or more beams to a target, an optical head (10) including a transmitting optics (12) and a collecting lens (14) for receiving one or more corresponding beam returns from the target. A detection system (18) includes a multi-element detector array at near a focal plane of the collecting lens. For each element of the multi-element detector array there is a specific optical path in the atmosphere leading from the laser to the target and back from the target to the element. A processor measures (20) signal fluctuations of an element of the multi-element detector array and computes therefrom crosswind velocity of wind in the atmosphere. The processor calculates turbulence strength changes.
