Optical-turbulence characterization of a littoral test environment using a Shack-Hartmann wavefront sensor

Timothy J. Bukowski,
Shannon O'Sullivan,
Matthew Kalensky
et al.

Abstract: Beam propagation systems are often used in a wide range of atmospheric environments. Therefore, it is important to be able to characterize those environments in order to appropriately assess performance and inform design decisions. In this paper, a variety of methods for measuring atmospheric coherence length, r0, were analyzed including a Shack–Hartmann-based differential image motion monitor (DIMM), gradient-tilt variance, slope discrepancy variance, and phase variance methods, as well as using the modulatio… Show more
