From: Effects of Optical Turbulence and Density Gradients on Particle Image Velocimetry

Energy spectra from PIV at LDA crossing for different optical turbulence strengths are consistent with spectra calculated from corresponding LDA data. The data are also consistent with spectra from velocity data collected with the Vectrino Profiler Acoustic Doppler Velocimeter (ADV) during a previous study for comparable turbulence strengths6.
