Title

Use Of A Shack-Hartmann Wave-Front Sensor To Measure Deviations From A Kolmogorov Phase Spectrum

Abstract

Experimental results indicate that the statistics of phase measured across a telescope aperture do not always obey the power laws associated with the Kolmogorov model of atmospheric turbulence. We show that the statistical relations between a wave front and its aperture-averaged f irst derivative previously derived for a Kolmogorov spectrum can be easily generalized for any power law. We also show that a Shack-Hartmann sensor can be used to measure the form of the structure function of phase f luctuations, and experimental data are presented. © 1995, Optical Society of America.
