任意平均温度、盐度和光波长下natural water turbulence的空间功率谱

Spatial power spectrum of natural water turbulence with any average temperature, salinity concentration and light wavelength

Jinren Yao, Mohammed Elamassie, Olga Korotkova

摘要:

水光学湍流的功率谱随其平均温度$\left\langle T \right\rangle$和平均盐度$\left\langle S \right\rangle$以及光波长$λ$而变化。本研究探讨了这种变化的$\left\langle T \right\rangle \in \left[ {0\ ^\circ\rm{C},30\ ^\circ\rm{C}} \right]$,$\left\langle S \right\rangle \in \left[ {0\ \rm{ppt},40\ \rm{ppt}} \right]$覆盖大多数可能的自然水条件下的地球边界层和可见光电磁波谱,$λ\in \left[400\ nm, 700\ nm \right]$。为了说明这些参数对传播光的影响,我们应用发达的功率谱模型估计的闪烁指数的平面波(Rytov方差)和弱和强湍流制度之间的阈值。

英文摘要:

The power spectrum of water optical turbulence is shown to vary with its average temperature $\left\langle T \right\rangle$ and average salinity concentration $\left\langle S \right\rangle$, as well as with light wavelength $λ$. This study explores such variations for $\left\langle T \right\rangle \in \left[ {0\ ^\circ\rm{C},30\ ^\circ\rm{C}} \right]$, $\left\langle S \right\rangle \in \left[ {0\ \rm{ppt},40\ \rm{ppt}} \right]$ covering most of the possible natural water conditions within the Earth's boundary layer and for visible electromagnetic spectrum, $λ\in \left[400\ nm, 700\ nm \right]$. 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.
