First on-sky results of the CO-SLIDAR C^2_n profiler

Abstract: Abstract:COupled SLope and scIntillation Detection And Ranging (CO-SLIDAR) is a recent profiling method of the vertical distribution of atmospheric turbulence strength (C 2 n profile). It takes advantage of correlations of slopes and of scintillation, both measured with a ShackHartmann wavefront sensor on a binary star. In this paper, we present the improved CO-SLIDAR reconstruction method of the C 2 n profile and the first on-sky results of the CO-SLIDAR profiler. We examine CO-SLIDAR latest performance in si… Show more

“…AOSH images simultaneously provide various data: slopes, intensities, and spot sizes. When short exposures are used, the information provided by both slopes and intensities (i.e., scintillation) can be used to retrieve Cn 2 profile using correlations of these data from two separated stars (Robert et al 2011;Voyez et al 2013). When long exposures are used, it is feasible to retrieve the atmospheric seeing in the line of sight from the spot sizes in the sub-apertures, with the advantage of being insensitive to the telescope field stabilization (Martinez et al 2012).…”

“…When temperature stratification is unstable under the convective boundary layer (CBL), especially within the well-mixed part ( 0.2 ∼ 0.8 z/z i , where z i is the height of CBL), the source of turbulence becomes mainly buoyancy-driven. Then, due to the nonlocal large-eddy heat flux, Equations ( 4)-( 6) and (10) that are based on K-theory failed to deal with the "zero/counter-gradient" region, where ∂Θ/∂z ≥ 0 while w θ > 0 [68,74]. Likewise, temperature structure constant C 2 T and refractive index structure constant C 2 n are not proportional to (dT/dz) 2 and M 2 anymore.…”

“…At present, there are some common methods for C 2 n detection. For instance, in areas of astronomy and satellite-ground laser communication, C 2 n profiles can be obtained by Slope Detection and Ranging (SLODAR) [9], Coupled Slope and Scintillation Detection and Ranging (CO-SLIDAR) [10], etc. [11][12][13].…”
