Abstract
Expressions for the variance and the power spectral density of turbule nce-induced Log-amplitude fluctuations are derived for Gaussian-beam w aves in the regime of weak scattering. This formulation includes effec ts that are due to turbulence strength variations along the propagatio n path, offset of the observation point from the beam axis, and sensit ivity to focus and beam diameter. Comparison of theoretical results wi th observed scintillation during experiments with a laser-illuminated satellite reveals good agreement. (C) 1995 Optical Society of America
