Paper Abstract

We have made high order (32x32 subaperture) Shack-Hartmann wavefront sensor observations of binary stars with separations of approximately 20 arcseconds using the University of Hawaii 2.2 m telescope. We present preliminary results of a Slope Detection and Ranging (SLODAR) analysis of the data yielding measurements of turbulence strength, wind velocity and velocity dispersion as a function of altitude, with approximately 500 m vertical resolution. The aim of the investigation is to explore the validity of the Taylor frozen flow approximation and the implications for layer-oriented predictive AO reconstruction algorithms.
