Fluctuations in backscattered signals due to turbulence in near-IR and visible lidar measurements

Spectral cross-correlation measurements performed in the near IR and in the visible, lambda(1) = 1.06 microm and lambda(2) = 0.53 microm, show that the main contribution to the fluctuations for the above lidar wavelengths originate in atmospheric turbulence. The measurements were performed in nonsat...

Description
Summary:Spectral cross-correlation measurements performed in the near IR and in the visible, lambda(1) = 1.06 microm and lambda(2) = 0.53 microm, show that the main contribution to the fluctuations for the above lidar wavelengths originate in atmospheric turbulence. The measurements were performed in nonsaturation conditions verified by an increase in the backscattered signal fluctuations with an increase in the target range. Normalized measurements as a function of daytime hours representing varying atmospheric turbulence conditions are presented and discussed.
