Abstract

A prototype atmospheric turbulence 'seeing' monitor was upgraded to provide a means of freezing, capturing, and digitizing up to 35,000 frames of two-dimensional image data at rates up to 350 frames per second with submillisecond exposure times. Analysis of this data is presented, yielding crucial information about the frequency spectra of turbulence-induced angle-of-arrival fluctuations. This information is used to establish a range of measurement parameters which are suitable for characterizing the statistical nature of the fluctuations and to establish a practical means for experimentally determining periods of atmospheric stationarity.
