Download or read book Optical Waves and Laser Beams in the Irregular Atmosphere written by Nathan Blaunstein and published by CRC Press. This book was released on 2017-09-22 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces optical wave propagation in the irregular turbulent atmosphere and the relations to laser beam and LIDAR applications for both optical communication and imaging. It examines atmosphere fundamentals, structure, and content. It explains specific situations occurring in the irregular atmosphere and for specific natural phenomena that affect optical ray and laser beam propagation. It emphasizes how to use LIDAR to investigate atmospheric phenomena and predict primary parameters of the irregular turbulent atmosphere and suggests what kinds of optical devices to operate in different atmospheric situations to minimize the deleterious effects of natural atmospheric phenomena.

Download or read book Field Guide to Atmospheric Optics written by Larry C. Andrews and published by Society of Photo Optical. This book was released on 2004 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material in this Field Guide is a condensed version of similar material found in two textbooks: Laser Beam Propagation through Random Media (SPIE Vol. PM53) and Laser Beam Scintillation with Applications (SPIE Vol. PM99). Topics chosen for this concise presentation include a review of classical Kolmogorov turbulence theory, Gaussian-beam waves in free space, and atmospheric effects on a propagating optical wave. These atmospheric effects have great importance in a variety of applications like imaging, free space optical communications, laser radar, and remote sensing. This Guide presents tractable mathematical models from which the practitioner can readily determine beam spreading, beam wander, spatial coherence radius (Fried's parameter), angle of arrival fluctuations, scintillation, aperture averaging effects, fade probabilities, bit error-rates, and enhanced backscatter effects, among others.

Book excerpt: This volume contains six review articles dealing with topics of current research interest in optics and in related fields. The first article deals with the so-called embedding method, which has found useful applications in the study of wave propagation in random media. The second article presents a review of an interesting class of non-linear optical phenomena which have their origin in the dependence of the complex dielectric constant of some media on the light intensity. These phenomena which include self-focusing, self-trapping and self-modulation have found many applications, for example in fibre optics devices, signal processing and computer technology. The next article is concerned with gap solitons which are electromagnetic field structures which can exist in nonlinear media that have periodic variation in their linear optical properties, with periodicities of the order of the wavelength of light. Both qualitative and quantitative descriptions of gap solitons are presented and some experimental schemes for their detection in the laboratory are discussed. The fourth article describes methods for the determination of optical phase from phase-modulated images. These methods have found applications in plasma diagnostics, in connection with flow characterisation and in the design of new optical instruments. The final article reviews developments relating to imaging, through turbulence in the atmosphere. It looks at the state-of-the-art of our understanding of this subject and discusses the most important methods that are presently employed to compensate for image distortion caused by atmospheric turbulence.

Available in PDF, EPUB and Kindle. Book excerpt: This monograph overviews classic and recent developments in theoretical statistical optics in connection with stationary and non-stationary (pulsed) optical source characterization and modeling, discusses various phenomena occurring with random light propagating in free space, on its interaction with optical systems, extended media and particulate collections. The text includes scalar, beam-like and general electromagnetic treatment of light. A brief statistical description of four fundamental experiments relating to random light: spatial and temporal field interference, intensity interferometry and phase conjugation, is also included in order to relate the analytical descriptions with practical observations.Rigorous mathematical methods for statistical manipulation of light sources useful for remote shaping of its various average properties, enhanced image resolution, optimized transmission in random media and for other applications are introduced. For illustration of efficient ways for manipulation of light polarization the generalized Stokes-Mueller calculus is applied for description of interaction of beam-like fields with classic and currently popular devices of polarization optics, including a spatial light modulator.Random light plays a special role in the image formation process. Three imaging modalities including the classic intensity-based system with structured source correlations, the polarization-based imaging system and the ghost interference approach are discussed in detail.Theoretical aspects of potential scattering of light from weakly scattering media are considered under a very broad range of assumptions: scalar/electromagnetic incident light, deterministic/random light/media, single/particulate media. Then, problems and methods in light characterization on interaction with extended, turbulent-like natural media, such as the Earth's atmosphere, oceans and soft bio-tissues that are currently widely used for communication, remote sensing and imaging purposes in these media, are provided.
Download or read book Experimental Investigations of Optical Propagation in Atmospheric Turbulence written by Michael W. Fitzmaurice and published by . This book was released on 1971 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pertinent theoretical background and the results of a group of experiments conducted over 0.4- and 1.17-km near-ground horizontal ranges are presented. (1) The log-amplitude variances for HeNe (0.633 μm) and CO2 (10.6 μm) laser beams were found to have a ratio of 26.8, which is in close agreement with the predictions of Rytov-based spherical-wave theory. (2) Published measurements of the saturation level of the log-amplitude variance are reviewed and several inconsistencies noted. (3) The spatial correlation function of irradiance field was measured and found to agree with theory. The degree of correlation between different frequency beams which had traversed the same optical path was also measured and compared to theory. The data exhibited an unacceptably large scatter and did not show the wavelength dependence. (4) The log-normal, Rayleigh, and Rice probability distributions are discussed in terms of their applicability to irradiance statistics. Relatively weak 10.6 μm irradiance fluctuations were found to be equally well described by the log-normal and Rice distributions; strong fluctuations obtained at 0.488 μm were clearly best described by the log-normal distribution.

Download or read book Optical Propagation in Linear Media written by Michael E. Thomas and published by Oxford University Press. This book was released on 2006-09-07 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: A typical optical system is composed of three basic components: a source, a detector, and a medium in which the optical energy propagates. Many textbooks cover sources and detectors, but very few cover propagation in a comprehensive way, incorporating the latest progress in theory and experiment concerning the propagating medium. This book fulfills that need. It is the first comprehensive and self-contained book on this topic. It is useful reference book for researchers, and a textbook for courses like Laser Light Propagation, Solid State Optics, and Optical Propagation in the Atmosphere.

There have been a number of new model developments in atmospheric propagation of a laser beam since the first edition of this Field Guide to Atmospheric Optics, many of which are included in this second edition. The subject of Atmospheric Optics is more extensive than that presented here. For example, most treatments of the subject matter concentrate heavily on the scattering and absorption by the molecular gases, particulates, and aerosols in the atmosphere. This usually also includes a detailed analysis of the wind, temperature, and pressure, particularly as a function of altitude. Another area of concentration in many treatments of the subject takes into account meteorological optics, which is a fascinating area all of its own. The subject of optical phenomena is often presented in great detail covering rainbows, halos, mirages, red sunsets, and so on" ...
