    Spatial power spectrum of natural water turbulence with any average temperature, salinity concentration, and light wavelength
    (The Optical Society, 2020-10-01) Yao, J. R.; Elamassie, Mohammed; Korotkova, O.; Electrical & Electronics Engineering; ELAMASSIE, Mohammed
    The power spectrum of water optical turbulence is shown to vary with its average temperature < T > and average salinity concentration < S >, as well as with light wavelength lambda. This study explores such variations for < T > is an element of [0 degrees C, 30 degrees C], < S > is an element of [0 ppt, 40 ppt] covering most of the possible natural water conditions within the Earth's boundary layer and for visible electromagnetic spectrum, lambda is an element of [400 nm, 700 nm]. For illustration of the effects of these parameters on propagating light, we apply the developed power spectrum model for estimation of the scintillation index of a plane wave (the Rytov variance) and the threshold between weak and strong turbulence regimes.
