Paper Abstract

The profile of atmospheric turbulence strength along a laser propagation or imaging path is thought to significantly influence performance. We use wave optics simulation to evaluate performance under random variations of turbulence profiles along a 50-km propagation path. Performance is given by power in the bucket (PIB) strehl in a (lambda) /D bucket. For a point source and under the conditions we investigated, we conclude that, in addition to the Rytov parameter, knowledge of r0 can significantly improve performance prediction.
