Pages : 29
Book Description
Several model aerosols of a given type, having the same visibility, but different yet reasonable microstructure, exhibit very wide dispersion, as much as 700%, in values of transmission at wavelengths from 2.0 to 10.6 micrometers. At near infrared wavelengths, from the visible to 2.0 micrometers, the dispersion is reduced, to a tolerable value of 10% at 1.06 micrometers. Two methods are suggested for exploiting the theoretical predictive techniques reported here. Results of a study designed to determine some of the effects of multiple scattering in low visibility situations (fog and a haze-soot mixture) indicate that laser system detectors of small solid angle register a transmission given very accurately by the single-scattering exponential transmission law, even for optical thickness greater than unity, but that detectors of large solid angle observe a considerably enhanced transmission for such optical depths. Also reported are results of two relevant but peripheral investigations, one concerning the application of dispersion relations to the complex reflectivity, the other concerning a necessary modification of radiative transfer theory under certain circumstances.
An Experimental System to Measure Atmospheric Extinction of Visible, Near and Far Infrared Radiation in the Marine Boundary Layer

Book Description
A method of measuring atmospheric extinction of radiation along a 13.3 kilometer path in the marine boundary layer has been devised and demonstrated. The design allows for selective measurement of extinction from the visible to the far infrared wavelengths. Two greybody sources, one covering the visible and near infrared and the other covering all bands out to the far infrared were each mounted on reflecting telescopes which were used to project the radiation. A reflecting telescope with selectable detectors was employed as the receiver. Two feasibility trials were conducted and the equipment was successfully calibrated. (Author).

Infrared Extinction and Standardization
Author: Quantitative Infrared Spectroscopy for Understanding of a Condensed Matter
Author: Takeshi HasegawaPublisher: Springer
ISBN: 4431564934
Category : Science
Languages : en
Pages : 207
Book Description
This book is intended to provide a course of infrared spectroscopy for quantitative analysis, covering both bulk matter and surface/interface analyses. Although the technology of Fourier transform infrared (FT-IR) spectroscopy was established many years ago, the full potential of infrared spectroscopy has not been properly recognized, and its intrinsic potential is still put aside. FT-IR has outstandingly useful characteristics, however, represented by the high sensitivity for monolayer analysis, highly reliable quantitativity, and reproducibility, which are quite suitable for surface and interface analysis. Because infrared spectroscopy provides rich chemical information—for example, hydrogen bonding, molecular conformation, orientation, aggregation, and crystallinity—FT-IR should be the first choice of chemical analysis in a laboratory. In this book, various analytical techniques and basic knowledge of infrared spectroscopy are described in a uniform manner. In particular, techniques for quantitative understanding are particularly focused for the reader’s convenience.

ISBN: 3319275143
Category : Science
Languages : en
Pages : 220
Book Description
This book provides a compact yet comprehensive overview of recent developments in collisional-radiative (CR) modeling of laboratory and astrophysical plasmas. It describes advances across the entire field, from basic considerations of model completeness to validation and verification of CR models to calculation of plasma kinetic characteristics and spectra in diverse plasmas. Various approaches to CR modeling are presented, together with numerous examples of applications. A number of important topics, such as atomic models for CR modeling, atomic data and its availability and quality, radiation transport, non-Maxwellian effects on plasma emission, ionization potential lowering, and verification and validation of CR models, are thoroughly addressed. Strong emphasis is placed on the most recent developments in the field, such as XFEL spectroscopy. Written by leading international research scientists from a number of key laboratories, the book offers a timely summary of the most recent progress in this area. It will be a useful and practical guide for students and experienced researchers working in plasma spectroscopy, spectra simulations, and related fields.
