Abstract
Phase diversity measurements using diffractive encoding systems offer a means for simultaneous measurement of the angular dependence of the turbulence induced in the wavefront distortion and either the angular dependence of scintillation induced during atmospheric propagation or the turbulence-degraded point spread function. We will describe experiments designed to measure the wavefront distortion and angular decorrelation of the atmospheric transfer functions, and discuss the observational strategy for measurement of atmospheric properties under a range of atmospheric conditions and propagation distances. By reconstructing the laser wavefront and comparing the calculated and measured images we will also aim to investigate the effect of strong scintillation on phase diversity wavefront reconstruction techniques. Laboratory tests of the equipment and preliminary measurements will be described, as well as some theory and modeling.
