Abstract

A simple grid of 10×10 white-light LEDs allows for simultaneous measurement of several characteristics of atmospheric turbulence. With this device, an imaging sensor and the model of tilt anisoplanatism one can determine turbulence strength, anisotropy, outer scale and spectral slope of turbulence. We describe the theory and present preliminary results obtained over a 270-m path.
