Aggregate Behavior of Branch Points - Branch Point Density as a Characteristic of an Atmospheric Turbulence Simulator (postprint)

摘要

The atmospheric turbulence simulator used in testing in the atmospheric simulation and adaptive-optic laboratory test-bed at Starfire Optical Range is configured based on three characteristics: Fried's parameter, the Rytov number and the Greenwood Frequency. All three may be estimated from open loop data as a means of verifying the simulated turbulence conditions for a given test configuration. However, unlike Fried's parameter and the Greenwood Frequency the Rytov number isn't directly calculated. Instead the scintillation index is estimated from intensity measurements. At low Rytov values.
