Analysis of turbulent atmospheric layers with a wavefront sensor: testing the frozen flow hypothesis

摘要

Abstract: We present a technique that can be used to quantify the frozen flow hypothesis with data from wavefront sensors such as those found in adaptive optics systems. The method is first tested with simulated data. Analyzing data from the 1.5-m and 3.5-m telescopes at the Starfire Optical Range, we then find that the frozen flow hypothesis is an accurate description of the temporal development of atmospheric turbulence on time scales on the order of 1-10 milliseconds, but that significant deviations from the frozen flow behavior are found for longer time scales. !19
