Abstract

Applications of adaptive optics to terrestrial imaging involve anisoplanatic imaging conditions in which the turbulence-distorted wavefront may be highly scintillated and have present phase discontinuities. We will describe experiments designed to assess these properties of the wavefront, and discuss the observational strategy for measurement of atmospheric properties under a range of atmospheric conditions and propagation distances. By reconstructing the 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.
