This book was released on 1974 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical results have been obtained for the effect of the strength of turbulence on the intensity, mutual coherence function, and frequency spectrum of a focussed beam propagating in a random medium having a von Karman spectrum for the index of refraction fluctuations. The author has presented conditions for when the turbulence affects the nature of the beam and has demonstrated the validity of these conditions by comparison with the numerical results. (Author).

This book was released on 2005 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since publication of the first edition of this text in 1998, there have been several new, important developments in the theory of beam wave propagation through a random medium, which have been incorporated into this second edition. Also new to this edition are models for the scintillation index under moderate-to-strong irradiance fluctuations; models for aperture averaging based on ABCD ray matrices; beam wander and its effects on scintillation; theory of partial coherence of the source; models of rough targets for ladar applications; phase fluctuations; analysis of other beam shapes; plus expanded analysis of free-space optical communication systems and imaging systems.

Book Synopsis The Theory of Scintillation with Applications in Remote Sensing by : Charles Rino
Download or read book The Theory of Scintillation with Applications in Remote Sensing written by Charles Rino and published by John Wiley & Sons. This book was released on 2011-03-08 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to truly understand data signals transmitted by satellite, one must understand scintillation theory in addition to well established theories of EM wave propagation and scattering. Scintillation is a nuisance in satellite EM communications, but it has stimulated numerous theoretical developments with science applications. This book not only presents a thorough theoretical explanation of scintillation, but it also offers a complete library of MATLAB codes that will reproduce the book examples. The library includes GPS coordinate manipulations, satellite orbit prediction, and earth mean magnetic field computations. The subect matter is for EM researchers; however, also theory is relevant to geophysics, acoustics, optics and astoronomy.

Book Synopsis Introduction to Applied Optics for Engineers by : F. Paul Carlson
Download or read book Introduction to Applied Optics for Engineers written by F. Paul Carlson and published by Elsevier. This book was released on 2012-12-02 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Applied Optics for Engineers introduces the reader to applied optics and presents ideas on coherent optical data processing. Topics covered include applications and approximations for radiation fields; physical realizations of phase transformers, lenses, and systems; applications of optical filtering to data processing; and partial coherence. Several examples from bioengineering-related research are provided. This book is comprised of 10 chapters and begins with an introduction to the basic equations of physical optics that are derived using the wave treatment approach, resulting in the simpler geometrical (ray) optics approximation. The differential form of Maxwell's equations is considered, along with propagation in free space and Fermat's principle. The following chapters explore applications and approximations for radiation fields, with emphasis on Fraunhofer fields, circular and multiple apertures, and phase effects in apertures; physical realizations of phase transformers, lenses, and spherical and parabolic surfaces; and system transform concepts including Fourier transform representation of fields and calculation techniques for imaging through a lens. The remaining chapters focus on interface devices, interferometry, holography, and scattering. This monograph is intended for students and engineers with a traditional background in electromagnetic wave theory.

Available in PDF, EPUB and Kindle. Book excerpt: When we were first approached by Dr. Lucky to write this book we were very enthusiastic about the prospect, since we had contemplated a similar project for quite some time. The difficulty lay in how best to digest the vast amount of data on optical propagation, reduce it to a book of manageable size, and simultaneously form the transition from the physics of propagation to the engineering of optical channels. This is the intent of Optical Channels. In accomplishing our goal it was necessary to condense the material on optical propagation and, in so doing, we have left a large amount to be handled via references. We have tried to make these decisions in a consistent manner so that the book will be uniform in its treatment of this topic. We identify four channels for consideration: the free-space channel, which: is characteristic of a tranquil atmosphere or a space-to-space link; the turbulent channel, which is characteristic of the atmospheric channel; the scatter channel in two forms, clouds and water; and the fiber optic channel. For each of these channels we have tried to reduce the applicable propagation theory to a level that can be used for engineering design. This has been done by example, but here again decisions had to be made on which examples to present. We have not tried to present any material on optical components and consequently other references on engineering would be necessary to supplement this book.
