Abstract

Development of a passive optical method for measuring the strength of atmospheric turbulence (atmospheric air refractive index structure constant C_n²) from image jitter is discussed. A high-rate digital camera and computer processing, including fast parallel 2D image correlation tracking algorithms, are shown to allow for real-time C_n² measurements. The results obtained by passive and active optical methods together with meteorological station support of the experiment are compared.
