Abstract

A Shack-Hartmann wavefront sensor placed at a pupil of an optical system can be used to measure atmospherically-induced wavefront aberrations across the pupil. This infromation can be used to reconstruct the phase of the wavefront and from that calculate a phase structure function. Of particular interest are measurements of the slope of the log of the structure function and the outer scale of the sutructure function.
