Atmospheric turbulence is an inevitable source of wavefront distortion in all fields of long range laser propagation and sensing. However, the distorting effects of turbulence can be corrected using wavefront sensors contained in adaptive optics syst

Optical turbulence, as determined by the widely accepted practice of profiling the temperature structure constant, CT2, via the measurement of ambient atmospheric temperature gradients, can be found to differ quite significantly when characterizing s

Knowledge of turbulence distribution along an experimental path can help in effective turbulence compensation and mitigation. Although scintillometers are traditionally used to measure the strength of turbulence, they provide a path-integrated measur

In this paper we compare results between three different turbulence measurement or estimation techniques. These approaches are: sonic anemometry; the MZA Path Resolved Optical Profiling System (PROPS); and a gradient technique using temperature and w

The refractive index structure constant, C 2n estimated by a DELTA system over water is compared to modeled values derived from numerical weather and observation data. Better results can be obtained if over the water air temperature is measured.
