Title: Intuitive model for the scintillations of a partially coherent beam

Abstract

We developed an intuitive model for the scintillation index of a partially coherent beam in which essentially the only critical parameter is the properly defined Fresnel number equal to the ratio of the “working” aperture area to the area of the Fresnel zone. The model transpired from and is supported by numerical simulations using Rytov method for weak fluctuations regime and Tatarskii turbulence spectrum with inner scale. The ratio of the scintillation index of a partially coherent beam to that of a plane wave displays a characteristic minimum, the magnitude of which and its distance from the transmitter are easily explained using the intuitive model. Furthermore, a theoretical asymptotic is found for the scintillation index of a source with decreasing coherence at this minimum.

Effects of residual coherence on the scintillation of a partially coherent beam

Journal Article Efimov, Anatoly - Optics Express

Recent results show that partially coherent beams (PCB) can be conveniently generated in a multimode fiber and modulated with data at gigabit per second rates, which makes them attractive for free-space optical communication through turbulent atmosphere. An important feature of these realistic beams in contrast to model ones is the presence of residual coherence between pairs of points spatially separated by more than a few coherence radii on the beam aperture. In the present work we experimentally study the influence of this residual coherence on the scintillation of a partially coherent beam in a laboratory turbulence. It is shown thatmore »« less

Gaussian beam scintillation index for slant path in weak turbulence: closed form expressions

Journal Article Aly, Asmaa M., E-mail: asma2.aly@gmail.com ; Fayed, Heba A., E-mail: hebam@aast.edu ; Ismail, Nour Eldin, E-mail: noureldin.hassan@alexu.edu.eg ; ... - Optical and Quantum Electronics

The scintillation index (SI) is an important issue in studying the effect of the atmospheric turbulence in the light waves. With the Rytov weak fluctuation theory, the SI is commonly referred to the Rytov parameter. The previous studies dealt with the plane wave and spherical wave models. Each of these gives an idea of how an optical beam will react to turbulence but are not realistic. One is infinitely long, while the other is an infinitesimal point source. The Gaussian beam wave is the most realistic of the optical waves, but also the most complex to use for calculations. Inmore »« less

Some new results on the statistics of radio wave scintillation 2. Scattering from a random ensemble of locally homogeneous patches

Journal Article Rino, C L - J. Geophys. Res.; (United States)

An analysis of scattering from an ensemble of locally homogeneous patches as described by Kolmogorov (1941) is presented. The analysis allows power law spectral density functions of the form kappa/sup -//subp/, where 2<4. Neither an outer scale nor an inner scale need be specified explicitly. It is shownc that there is a Fresnel radius dependence of the scattering cross section that acts to increase the quadratic wavelength dependence that characterizes the usual strictly homogeneous scattering. For spectral p indices between the Kolmogorov value p=11/3 and the limiting value p=4 good agreement is found between the theory and the ionospheric scintillationmore »« less

Log-amplitude variance and wave structure function: A new perspective for Gaussian beams

Journal Article Miller, W B ; Ricklin, J C ; Andrews, L C - Journal of the Optical Society of America, Part A: Optics and Image Science; (United States)

Two naturally linked pairs of nondimensional parameters are identified such that either pair, together with wavelength and path length, completely specifies the diffractive propagation environment for a lowest-order paraxial Gaussian beam. Both parameter pairs are intuitive, and within the context of locally homogeneous and isotropic turbulence they reflect the long-recognized importance of the Fresnel zone size in the behavior of Rytov propagation statistics. These parameter pairs, called, respectively, the transmitter and receiver parameters, also provide a change in perspective in the analysis of optical turbulence effects on Gaussian beams by unifying a number of behavioral traits previously observed or predicted,more »« less

Partially coherent migration

Journal Article Lee, D ; Jackson, G M ; Mason, I M - Geophysics; (United States)

Partially coherent migration reduces the spurious details introduced by velocity macro-model imperfections. In a partially coherent migration, instead of summing coherently over the full aperture to achieve maximum lateral resolution, (1) a coherent stack is performed over a limited window width, and then (2) the collection of coherent stacks for different windows along the full aperture are summed incoherently to produce an amplitude value for each output point. Amplitude accuracy of a migration is improved with some sacrifice in spatial (lateral) resolution. A parameter in partially coherent migration is the running coherent window width, which accounts for the spatial correlationmore »« less
