Adaptive Beaming And Imaging In The Turbulent Atmosphere

by Vladimir Petrovich Lukin, release date 2002, Adaptive Beaming And Imaging In The Turbulent Atmosphere Books available in PDF, EPUB, Mobi Format. Download Adaptive Beaming And Imaging In The Turbulent Atmosphere books, Due to the wide application of adaptive optical systems, an understanding of optical wave propagation in randomly inhomogeneous media has become essential, and several numerical models of individual AOS components and of efficient correction algorithms have been developed. This monograph contains detailed descriptions of the mathematical experiments that were designed and carried out during more than a decade's worth of research.

Applied Aspects Of Optical Communication And Lidar

by Nathan Blaunstein, release date 2009-12-28, Applied Aspects Of Optical Communication And Lidar Books available in PDF, EPUB, Mobi Format. Download Applied Aspects Of Optical Communication And Lidar books, Exploring the practical aspects of atmospheric optical communication and light detection and ranging (LIDAR), Applied Aspects of Optical Communication and LIDAR details the role of atmospheric structures in propagation phenomena that influence the transmission of optical signals through perturbed atmospheric communication channels. It examines numerous situations in over-the-terrain atmospheric communication channels, including the effects of natural phenomena and the corresponding features (turbulences and hydrometeors) on optical ray propagation. Bridging the gap between the parameters of optical communication links and signal information data streams, this concise reference addresses line-of-sight (LOS) as well as obstructive non-line-of-sight (NLOS) propagation conditions. It also: Details the main characteristics of optical communication channels Introduces the quasi-regular gaseous atmosphere Describes numerous situations in the atmospheric communication channel Explains the main characteristics of optical communication channels Complete with parameters for information data streams, the text also provides time-saving suggestions for determining which optical devices will work best for minimizing the deleterious effects of natural atmospheric phenomena. Whether you’re a researcher, an engineer, or student—this book provides you with the practical understanding required to use LIDAR to investigate all forms of atmospheric phenomena and to learn how to accurately predict primary parameters of atmospheric optical channels.

Adaptive Optics For Astronomical Telescopes

by John W. Hardy, release date 1998, Adaptive Optics For Astronomical Telescopes Books available in PDF, EPUB, Mobi Format. Download Adaptive Optics For Astronomical Telescopes books, This book by one of the leaders in adaptive optics covers the fundamental theory and then describes in detail how this technology can be applied to large ground-based telescopes to compensate for the effects of atmospheric turbulence. It includes information on basic adaptive optics components and technology, and has chapters devoted to atmospheric turbulence, optical image structure, laser beacons, and overall system design. The chapter on system design is particularly detailed and includes performance estimation and optimization. Combining a clear discussion of physical principles with numerous real-world examples, this book will be a valuable resource for all graduate students and researchers in astronomy and optics.

General Theory Of Light Propagation And Imaging Through The Atmosphere

by T. Stewart McKechnie, release date 2015-08-05, General Theory Of Light Propagation And Imaging Through The Atmosphere Books available in PDF, EPUB, Mobi Format. Download General Theory Of Light Propagation And Imaging Through The Atmosphere books, This book lays out a new, general theory of light propagation and imaging through Earth’s turbulent atmosphere. Current theory is based on the – now widely doubted – assumption of Kolmogorov turbulence. The new theory is based on a generalized atmosphere, the turbulence characteristics of which can be established, as needed, from readily measurable properties of point-object, or star, images. The pessimistic resolution predictions of Kolmogorov theory led to lax optical tolerance prescriptions for large ground-based astronomical telescopes which were widely adhered to in the 1970s and 1980s. Around 1990, however, it became clear that much better resolution was actually possible, and Kolmogorov tolerance prescriptions were promptly abandoned. Most large telescopes built before 1990 have had their optics upgraded (e.g., the UKIRT instrument) and now achieve, without adaptive optics (AO), almost an order of magnitude better resolution than before. As well as providing a more comprehensive and precise understanding of imaging through the atmosphere with large telescopes (both with and without AO), the new general theory also finds applications in the areas of laser communications and high-energy laser beam propagation.
