Book Synopsis Atmospheric Attenuation of CO Laser Radiation by : R. A. McClatchey
Download or read book Atmospheric Attenuation of CO Laser Radiation written by R. A. McClatchey and published by . This book was released on 1971 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of the CO laser having emission lines in the range from 1200/cm to greater than 2000/cm, it is of importance to establish which of the more than 200 lines can be transmitted through a variety of atmospheric paths. The spectral region of CO emission spans a very important water vapor absorption band and, in addition, there is absorption by CO2, O3, N2O and CH4. Absorption lines associated with all of these molecules were included in the calculation of synthetic spectra covering the region of CO emission. After limiting the number of CO emission lines to be considered in detail according to a criterion based on atmospheric attenuation, a series of tables was constructed providing quantitative attenuation information for each of 88 laser lines and for 10 different atmospheric models. Data based on two different aerosol scattering models are included in these tables. (Author).
Book Synopsis Atmospheric Attenuation of Laser Radiation from 0.76 to 31.25 Micrometers by : R. A. McClatchey
Download or read book Atmospheric Attenuation of Laser Radiation from 0.76 to 31.25 Micrometers written by R. A. McClatchey and published by . This book was released on 1974 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: High resolution atmospheric transmittance curves are presented for the spectral region 320 to 13,200/cm (0.7576 to 31.25 micrometers). These spectra are useful as a guide for selecting laser wavelengths for atmospheric propagation studies in this spectral region. In addition, this report provides attenuation coefficients for those lines of the CO, HF, DF, and CO2 laser systems which suffer the least atmospheric attenuation. A new aerosol model is introduced here, taking into account recent measurements of the complex index of refraction of aerosol particles. (Author).

Book Synopsis Atmospheric Attenuation of HF and DF Laser Radiation by : Robert A. McClatchey
Download or read book Atmospheric Attenuation of HF and DF Laser Radiation written by Robert A. McClatchey and published by . This book was released on 1972 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of HF and DF lasers having emission lines in the range from 2800 to 3700/cm−1 (HF) and 2000 to 2750/cm−1 (DF), it is of importance to establish which of the more than 100 lines can be transmitted through a variety of atmospheric paths. The spectral region of HF emission spans a very important water vapor absorption band and, in addition, there is strong absorption by CO2 and weaker absorption by ozone and methane. The spectral region of DF emission covers the very strong 4.3 micrometer CO2 absorption band and weaker absorption by N2O and HDO at higher frequencies (low DF vibrational transitions). There is some weak ozone absorption also in the region of DF emission. Absorption lines associated with all of these molecules were included in the calculation of synthetic spectra covering the region of HF and DF emission. After limiting the number of emission lines to be considered in detail according to a criterion based on atmospheric attenuation, a series of tables was constructed providing quantitative attenuation information for each of 97 laser lines and for 10 different atmospheric models. Data based on two different aerosol scattering models are included in these tables.

Book Synopsis CO2 Laser Radiation Absorption in SF6 -air Boundary Layers by : John David Anderson (Jr.)
Download or read book CO2 Laser Radiation Absorption in SF6 -air Boundary Layers written by John David Anderson (Jr.) and published by . This book was released on 1972 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous investigators have shown that gaseous sulfur hexafluoride (SF6) is a strong absorber of radiation at 10.6 micrometers. This wavelength also corresponds to the output from common CO2 lasers. New experimental and theoretical results are presented for the 10.6 micrometers absorption coefficient and saturation properties of SF6-air mixtures at conditions near standard sea level. Variations with pressure, wavelength and temperature are measured. Results for 10 percent SF6-90 percent air at 1 atm show that such mixtures are stron absorbers of CO2 laser radiation, and that saturation intensities are larger than 10,000 watts/sq cm. Measurements of CO2 laser radiation absorption within boundary layers with SF6 injection are made on the sidewall of a small subsonic wind tunnel. The beam intensity is attenuated by several orders of magnitude due to absorption by the SF6. (Author).

Book Synopsis An Introduction To Solar Radiation by : Muhammad Iqbal
Download or read book An Introduction To Solar Radiation written by Muhammad Iqbal and published by Elsevier. This book was released on 2012-12-02 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Solar Radiation is an introductory text on solar radiation, with emphasis on the methods of calculation for determining the amount of solar radiation incident on a surface on the earth. Topics covered include the astronomical relationship between the sun and the earth; thermal radiation; the solar constant and its spectral distribution; and extraterrestrial solar irradiation. This book is comprised of 12 chapters and begins with an overview of the trigonometric relationships between the sun-earth line and the position of an inclined surface, followed by a discussion on the characteristics of blackbody radiation. The next chapter focuses on the solar constant and its spectral distribution, paying particular attention to extraterrestrial solar spectral irradiance and the sun's blackbody temperature. Subsequent chapters explore extraterrestrial and radiation incident on inclined planes; the optics of a cloudless-sky atmosphere; solar spectral radiation and total (broadband) radiation under cloudless skies; and solar radiation arriving at horizontal surfaces on the earth through cloudy skies. The ground albedo and its spectral and angular variation are also described, along with insolation on inclined surfaces. The last chapter is devoted to instruments for measuring solar radiation, including pyrheliometers and pyranometers. This monograph will serve as a useful guide for energy analysts, designers of thermal devices, architects and engineers, agronomists, and hydrologists as well as senior graduate students.
Book Synopsis Spectrometric Techniques by : George A. Vanasse
Download or read book Spectrometric Techniques written by George A. Vanasse and published by Elsevier. This book was released on 2013-10-22 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectrometric Techniques, Volume III presents the applications of spectrometric techniques to atmospheric and space studies. This book reviews the spectral data processing and analysis techniques that are of broad applicability. Organized into five chapters, this volume begins with an overview of the instrumentation used for obtaining field data. This text then reviews the contribution that space-borne spectroscopy in the thermal IR has made to the understanding of the planets. Other chapters consider the instruments that have recorded the planetary emission spectra. This book discusses as well the interpretation of planetary IR spectra based on the theory of radiative transfer, which describes the interaction of electromagnetic radiation with matter. The final chapter deals with a few practical remarks on calculation of the inverse-filtered spectrum, wherein the Fourier transform of the data is divided by the Fourier transform of the impulse response function for the low frequencies. This book is a valuable resource for spectroscopists and scientists.

Book Synopsis Safety with Lasers and Other Optical Sources by : D. H. Sliney
Download or read book Safety with Lasers and Other Optical Sources written by D. H. Sliney and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 1042 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly a decade aga a general review article on the evaluation of optical radia tion hazards was published in Applied Optics (Sliney and Freasier, 1973). This arti cle received many favorable comments but also prompted many inquiries regarding specific optical hazard problems. From this it became evident that a monograph rather than a supplemental and expanded article was needed to fill this literature gap relating to laser and optical radiation hazards. The present work is designed to fill that gap, and is structured to permit either classroom or self-study use. Much of the material in this book was developed in eonnection with short courses on laser safety and radiometry in which we have participated, as weIl as from our previous articles. In particular, the sequenee of chapters is based upon the experiences which we have had in lecturing in courses with different schedules. One of the great difficulties in developing a text of this nature is that a broad, multidisciplinary background must be included in order that the reader can comprehend all of the subjeet matter readily. For this reason, the material presented on anatomy and physiology is orien ted toward the engineer or physical scientist, while the review material on basic optical physics is intended more for the physician or life scientist.
