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

Sonic anemometers are used to study the outer scale in near ground level turbulence. Turbulence is expected to obey a Kolmogorov power spectrum within some inertial range, where the temperature or index of refraction fluctuations decrease as the inve

Understanding how atmospheric turbulence is distributed along a path helps in effective turbulence compensation and mitigation. Phase-based techniques to measure turbulence have potential advantages when used over long ranges since they do not suffer

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

A dual-beacon Hartmann Turbulence Sensor (HTS) was used to estimate atmospheric turbulence profiles along a 1.8 km long slant path. This HTS uses a 16“ telescope and has 700 active subapertures. Its camera can take frames as fast as 8 kHz. The lase

Atmospheric turbulence profiles were estimated for a horizontal path based upon measurements made with a dual beacon Hartmann Turbulence Sensor (HTS) using simulation derived weighting functions. These results are compared to estimates made using a w

Previous turbulence measurements along a near-ground, 500 m, horizontal path using two helium-neon laser beacons and a Hartmann Turbulence Sensor (HTS) yielded profiles of Cn^2 by measuring local aberrated wavefront tilts. The profiles were consisten
