Abstract

Estimating the prole of the index of refractive-index structure constant, C²_n(z), is of great importance for characterizing the turbulence through which adaptive optical systems operate. Stereo Scintillation Detection and Ranging (SCIDAR) is one of the well developed techniques for making such a prole using light from binary stars. The Air Force Research Laboratory's Starre Optical Range (SOR) is beginning work to add a Stereo SCIDAR capability to the site. This work presents the development and testing of a stereo SCIDAR system in the Atmospheric Simulation and Adaptive Optics Laboratory Testbed (ASALT) at SOR. The stereo SCIDAR system was constructed on the ASALT lab's Multiconjugate Adaptive Optics (MCAO) bench, which features an enhanced atmospheric turbulence simulator (ATS) that can use up to 10 phase screens to test the capabilities of the stereo SCIDAR system in profiling distributed turbulence under a wide range of conditions.
