Aperture Averaging of Saturated Scintillation of Laser Propagation in the Atmosphere
The characteristics of the temporal spectrum of optical scintillation in a finite aperture in the turbulent atmosphere are analyzed theoretically. Experiments of laser scintillation in a pinhole and a 260 mm aperture were carried out along a 6.8 km propagation path. Comparisons of scintillation spectra and standard deviations are made between those for the pinhole and the 260 mm aperture. It can be concluded that the aperture averaging can be saturation-resistant for the saturation to some extent. This provides a foundation for measuring optical turbulence intensity using scintillation in a finite aperture.
