Abstract
Temporal-frequency spectra are produced from irradiance measurements of a laser beam after propagation along a 16 km path on the Chesapeake Bay. DC-coupled detectors of 3 coaxial receivers of diameter 12, 25 and 50mm were continuously recorded at 2 kHz. These high-speed raw data supplemented the usual turbulence parameters recorded at the laser test bed. A scalable automated process was developed for extracting salient features of the power spectra such as slopes and knee frequencies. The relevance of these key features will be discussed in relation to the inertial and dissipation regions of turbulence.
