Abstract

An implementation of differential scintillations to characterize the C²_n(z) profile along a nearly horizontal propagation path measured by a Shack-Hartmann wavefront sensor is developed and demonstrated. Measurements from a Small Mobile Atmospheric Sensing Hartmann (SMASH) instrument using an LED source to characterize 500 m, 1 km and 2 km paths at the Environmental Laser Test Facility (ELTF) are presented.
