差频瑞利增强极化拍频研究
Difference-Frequency Rayleigh-Enhanced Polarization Beats
摘要
基于马尔可夫随机场模型的理论给出了差频瑞利增强极化拍(REPB)的解析解,并且研究了三种马尔可夫随机场模型下场关联效应和瑞利型共振增强效应对拍频信号的影响,指出了振幅涨落和位相涨落在时域和频域的不同作用.差频REPB信号展现出了时域对称特性,信号在三种马尔可夫随机场模型下的差别随着带宽的增大逐渐消失.
Abstract
The theoretical analysis based on three Markovian stochastic models provides a closed-form solution for the difference-frequency Rayleigh-enhanced polarization beats. The subtle Markovian field correlation effects have been investigated. The different roles of the amplitude fluctuations and the phase fluctuations have been pointed out both in time-and frequency-domains. The difference-frequency REPB signal shows symmetric temporal behavior,and differences among three Markovian stochastic fields are quite sensitive to the change of bandwidth,and as the bandwidth increases,the difference becomes obscure.
