Turbulence characterization with a Shack-Hartmann wavefront sensor

SPIE Newsroom, 2010
In the field of optical atmospheric propagation, knowledge of optical-turbulence strength and other key statistical parameters is crucial for performance prediction and system design. Hartmann-sensor data can be used to reliably estimate the essential parameters characterizing optical turbulence, including the Fried coherence length (r0), the Greenwood
