Book Synopsis Measurements of 0.63mm Laser-beam Scintillation in Strong Atmospheric Turbulence by : G. R. Ochs
Download or read book Measurements of 0.63mm Laser-beam Scintillation in Strong Atmospheric Turbulence written by G. R. Ochs and published by . This book was released on 1969 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Log-amplitude variance and covariance of the scintillation of a diverging optical beam have been measured over a 48-hr period at a wavelength of 0.63[mu], on a 490 and 1000 m optical paths 2 m above the surface of a flat mesa near Boulder, Colorado. Simultaneous measurements of the refractive-index structure of the atmosphere have been obtained from temperature-structure-function measurements at spacings of 1, 3, and 10 cm. A saturation of scintillation occurs for values of log-amplitude variance between 0.5 and 1. After reaching a peak, the log-amplitude variance then decreases with both increasing range and increasing refractive-index turbulence. The spatial covariance of the fluctuations tends to increase in the saturation region. In the unsaturated region, the log-amplitude variance is approximately that predicted by the spherical-wave propagation theory of Tatarski.

Book Synopsis Laser Beam Shaping Applications by : Fred M. Dickey
Download or read book Laser Beam Shaping Applications written by Fred M. Dickey and published by CRC Press. This book was released on 2005-07-26 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practice of shaping the irradiance profile of laser beams goes back more than three decades, and the applications of beam shaping are as diverse as they are numerous. However, until Dickey and Holswade's groundbreaking and highly popular Laser Beam Shaping: Theory and Techniques was published, there was no single, detailed treatment available on the underlying theory and basic techniques of beam shaping. Building on the foundations of this previous work, these esteemed editors have teamed with recognized expert David L. Shealy to produce the first in-depth account of beam shaping applications and design. Laser Beam Shaping Applications details the important features of beam shaping and exposes the subtleties of the theory and techniques that are best demonstrated through proven applications. In chapters contributed by prominent, active leaders in their respective specialties, the book discusses applications in lithography, laser printing, optical data storage, stable isotope separation, adaptive mirrors, and spatially dispersive lasers. The contributors share major insights, knowledge, and experience, reveal the advantages of the technologies, and include extensive references to the literature. The book concludes with a summary of beam shaping theory and techniques as well as the history of the field. Providing practical expertise, Laser Beam Shaping Applications is an extremely helpful guide to improving current laser processes, optimizing application-specific technologies, and advancing future development in the field.

Book Synopsis Laser Beam Scintillation in the Marine Boundary Layer by : Brian Christian Haagensen
Download or read book Laser Beam Scintillation in the Marine Boundary Layer written by Brian Christian Haagensen and published by . This book was released on 1973 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensity scintillation in a laser beam at 0.63 micrometers in the marine boundary layer has been studied over a 4.3 kilometer horizontal path across Monterey Bay and also from shore to ship at San Nicolas Island. Optical and micrometeorological measurements of the refractive index structure constant, C(N), agree to approximately one standard deviation giving values in the range of 2.0 x 10 to the minus 8th power to 5.0 x 10 to the minus 8th power ((meters) to the minus 1/3 power). Optical and meteorological data correlation improved as mean wind speed increased. Evidence was found to support the reported existence of a saturation region for the laser beam logarithmic amplitude variance. (Author).

Book Synopsis Spectral Density of Laser Beam Scintillation in Wind Turbulence. Part 1; Theory by : National Aeronautics and Space Administration (NASA)
Download or read book Spectral Density of Laser Beam Scintillation in Wind Turbulence. Part 1; Theory written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-11 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The temporal spectral density of the log-amplitude scintillation of a laser beam wave due to a spatially dependent vector-valued crosswind (deterministic as well as random) is evaluated. The path weighting functions for normalized spectral moments are derived, and offer a potential new technique for estimating the wind velocity profile. The Tatarskii-Klyatskin stochastic propagation equation for the Markov turbulence model is used with the solution approximated by the Rytov method. The Taylor 'frozen-in' hypothesis is assumed for the dependence of the refractive index on the wind velocity, and the Kolmogorov spectral density is used for the refractive index field.
