About the Author
Larry C. Andrews is Professor Emeritus of Mathematics at the University of Central Florida and an associate member of the Townes Laser Institute in the College of Optics/CREOL. He previously was also an associate member of the Florida Space Institute (FSI) and had a joint faculty appointment with the Department of Electrical and Computer Engineering. Before that, he held a faculty position at Tri-State University and was a staff mathematician with the Magnavox Company s anti-submarine warfare (ASW) operation. He received a doctoral degree in theoretical mechanics in 1970 from Michigan State University. Dr. Andrews has been an active researcher in optical wave propagation through random media for more than 35 years and is the author or co-author of twelve textbooks on topics of differential equations, boundary value problems, special functions, integral transforms, wave propagation through random media, and mathematical techniques for engineers. He is a Fellow of SPIE and the author of three SPIE Field Guides (on Atmospheric Optics, Special Functions, and Random Processes). Along with wave propagation through random media, his research interests include special functions, random variables, atmospheric turbulence, and signal processing.
This second edition of the Field Guide to Atmospheric Optics contains several new developments in atmospheric propagation through the atmosphere since publication of the first edition (2004). Some of these new topics include the HAP [i]C[sub]n[/sub][/i][sup]2[/sup] profile model, ABCD ray matrices, beam-wander-induced scintillation, phase fluctuations, round-Earth model, analytic models for enhanced backscatter off of semi-rough targets, and non-Kolmogorov anisotropic models. As in the first edition, this Field Guide includes a review of classical Kolmogorov theory, Gaussian-beam waves in free space, and tractable atmospheric propagation models for the second-order and fourth-order field moments known, respectively, as the mutual coherence function and fourth-order cross-coherence function. Specializations of these general field moments allow the practitioner to easily calculate beam spreading, beam wander, spatial coherence (the Fried parameter), angle-of-arrival fluctuations, scintillation index, aperture-averaging effects, fade probabilities, bit error rates, and enhanced backscatter effects, among others. Knowledge of these mathematical models is important in many applications like imaging, free-space optical communications, and laser radar.
