Abstract
The Reflective Atmospheric Turbulence Simulator (RATS) is an instrument used to simulate the propagation of light through atmospheric turbulence. RATS can simulate up to six layers of atmospheric turbulence using reflective phase wheels with many configurations that can simulate a broad range of atmospheric turbulence conditions. Two ShackHartmann wavefront sensors are integrated with RATS. One of these Shack-Hartmann wavefront sensors has an effective aperture size of 40cm, and the other has an effective aperture size of 6.75cm. We simulated propagation through atmospheric turbulence using RATS and made measurements of turbulence parameters using the two Shack-Hartmann wavefront sensors. In this paper, we compare the measurements of turbulence parameters from both Shack-Hartmann wavefront sensors to each other as well as to the theoretical values for atmosphere turbulence simulated by RATS.
