舰船尾流气泡多重散射偏振特性研究

摘要

Multiple scattering effect about Ship wake bubble is important for optical wake detection.Aiming at the effect of multiple bubble scattering on backscattering light intensity and degree of polarization,the polarization state of the photon was tracked by Euler vector method.Under the incident conditions of linearly polarized light and circularly polarized light,the characteristics difference was analyzed,which the different echo signals produce in the backward scattering light intensity and the degree of polarization,and the feasibility that the Euler vector method is used to optical wake of detection field is verified.%舰船尾流气泡的多次散射效应对光尾流探测领域的研究具有重要意义.针对水中气泡多次散射对后向散射光强以及偏振度的影响规律问题,基于矢量Monte Carlo方法,采用欧拉矢量法对光子在水中气泡后向散射偏振态进行跟踪,对比分析了线偏振、圆偏振激光入射情况下,不同散射次数回波信号在强度和偏振度特性上的差异性,验证了欧拉矢量法用于光尾流探测仿真领域的可行性.
