Power Spectra Analysis of the Disturbed Wavefront in Laser Beam Horizontal Atmospheric Propagation II: Wavefront Phase and Greenwood Frequency
By using the Hartmann-Shack wavefront sensor of the 61 element adaptive optical system, power spectra density (PSD) of the atmosphere disturbed wavefront, both overall tilt removed and leave in, was measured and analyzed. A method of calculating the Greenwood frequency and the needed control bandwidth of the deformable mirror of an adaptive optical system from measured PSDs was discussed.
