Abstract

Laboratory measurements of light beam depolarization by a turbulent flow, corresponding to oceanic turbulence within the oceanic mixed layer, show that the depolarization rate (1x10(-5)?m(-1) to 3x10(-3)?m(-1)) correlates with turbulence strength and is consistent with polarized lidar observations [Opt. Express, 16, 1196 (2008)OPEXFF1094-408710.1364/OE.16.001196]. These results imply that one should be able to characterize oceanic turbulence with polarimetric oceanic lidar measurements.

摘要

对与海洋混合层内的海洋湍流相对应的湍流引起的光束去极化进行的实验室测量表明,去极化率(1×10⁻⁵ m⁻¹至3×10⁻³ m⁻¹)与湍流强度相关,并且与偏振激光雷达观测结果一致[《光学快报》,16,1196 (2008)OPEXFF1094 - 408710.1364/OE.16.001196]。这些结果意味着应该能够通过偏振海洋激光雷达测量来表征海洋湍流。
