Available in PDF, EPUB and Kindle. Book excerpt: Many applications today require the Fourier-transform (FT) spectrometer to perform close to its limitations, such as taking many quantitative measurements in the visible and in the near infrared wavelength regions. In such cases, the instrument should not be considered as a perfect "black box." Knowing where the limitations of performance arise and which components must be improved are crucial to obtaining repeatable and accurate results. One of the objectives of this book is to help the user identify the instrument's bottleneck.

This book was released on 2010 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The remote sensing gas detection problem is on with no straightforward solution. While success has been achieved in detecting and identifying gases released from industrial stacks and other large plumes, the fugitive gas detection problem is far more complex. Fugitive gas represents a far smaller target and may be generated by leaking pipes, vents, or small scale chemical production. The nature of fugitive gas emission is such that one has no foreknowledge of the location, quantity, or transient rate of the targeted effluent which requires one to cover a broad area with high sensitivity. In such a scenario, a mobile airborne platform would be a likely candidate. Further, the spectrometer used for gas detection should be capable of rapid scan rates to prevent spatial and spectral smearing, while maintaining high resolution to aid in species identification. Often, insufficient signal to noise (SNR) prevents spectrometers from delivering useful results under such conditions. While common dispersive element spectrometers (DES) suffer from decreasing SNR with increasing spectral dispersion, Fourier Transform Spectrometers (FTS) generally do not and would seemingly be an ideal choice for such an application. FTS are ubiquitous in chemical laboratories and in use as ground based spectrometers, but have not become as pervasive in mobile applications. While FTS spectrometers would otherwise be ideal for high resolution rapid scanning in search of gaseous effluents, when conducted via a mobile platform the process of optical interferogram formation to form spectra is corrupted when the input signal is temporally unstable. This work seeks to explore the tradespace of an airborne Michelson based FTS in terms of modeling and characterizing the performance degradation over a variety of environmental and optical parameters. The major variables modeled and examined include: maximum optical path distance (resolution), scan rate, platform velocity, altitude, atmospheric and background emissivity variability, gas target parameters such as temperature, concentration-pathlength, confuser gas presence, and optical effects including apodization effects, single and double-sided interferograms, internal mirror positional accuracy errors, and primary mirror jitter effects. It is through an understanding of how each of the aforementioned variables impacts the gas detection performance that one can constrain design parameters in developing and engineering an FTS suitable to the airborne environment. the instrument model was compared to output from ground-based FTS instruments as well as airborne data taken from the Airborne Hyperspectral Imager (AHI) and found to be in good agreement. Monte Carlo studies were used to map the impact of the performance variables and unique detection algorithms, based on common detection scores, were used to quantify performance degradation. Scene-based scenarios were employed to evaluate performance of a scanning FTS under variable and complex conditions. It was found that despite critical sampling errors and rapidly varying radiance signals, while losing the ability to reproduce a radiometrically accurate spectrum, an FTS offered the unique ability to reproduce spectral evidence of a gas in scenarios where a dispersive element spectrometer (DES) might not."--Abstract.
Download or read book Fourier Transform Infrared Spectra written by John R. Ferraro and published by Academic Press. This book was released on 2012-12-02 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The final and largest volume to complete this four-volume treatise is published in response to the intense commercial and research interest in Fourier Transform Interferometry.Presenting current information from leading experts in the field, Volume 4 introduces new information on, for example, applications of Diffuse Reflectance Spectroscopy in the Far-Infrared Region. The editors place emphasis on surface studies and address advances in Capillary Gas Chromatography - Fourier Transform Interferometry.Volume 4 especially benefits spectroscopists and physicists, as well as researchers in physical, analytical, and surface chemistry.FROM THE PREFACE: Several reasons can be cited for the need to publish Volume 4 in this treatise.First, interest in Fourier transform interferometry (FT-IR) has continued. The number of commercial manufacturers of FT-IR instrumentation has increased, reflecting the increase in demand for such instrumentation. The main thrust in FT-IR instrumentation has focused on applications, and many techniques using FT-IR instrumentation have been generated in order to solve problems heretofore unsolvable. The interest in surfaces relative to catalysts, polymers, and electrical conductors has escalated. Three chapters in Volume 4 are devoted to surfaces. Second, the great acceptance of Volumes 1 through 3 and the demand to continue the treatise have induced us to publish Volume 4.The present volume contains nine chapters, making it the largest of the four volumes. Chapter 1 deals with infrared data processing techniques. Chapter 2 concerns itself with circular dichroism*b1FT-IR. Chapter 3 presents an update on GC*b1FT-IR, a rapidly moving field. Chapter 4 deals with the combination of FT-IR and thermal analysis. Advances in coal analyses using FT-IR are presented in Chapter 5. Reflectance studies are highlighted in Chapters 6, 7, and 8. Chapter 6 deals with structural characterizations made with Langmuir*b1Blodgett monolayers. Also in Chapter 6, the extension of DRIFT into the far-infrared region is shown to be feasible and valuable. Reflection*b1absorption surface studies (FT-IRRAS) are discussed in Chapter 8. Chapter 9 updates us on photoacoustic spectroscopy*b1FT-IR.All of the contributions are made by working experts in these areas. It is the hope that Volume 4 continues in the spirit of the purpose of these volumes, namely, to keep the scientific communities abreast of new developments in FT-IR as applied to chemical systems.

Download or read book Introductory Fourier Transform Spectroscopy written by Robert Bell and published by Elsevier. This book was released on 2012-12-02 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introductory Fourier Transform Spectroscopy discusses the subject of Fourier transform spectroscopy from a level that requires knowledge of only introductory optics and mathematics. The subject is approached through optical principles, not through abstract mathematics. The book approaches the subject matter in two ways. The first is through simple optics and physical intuition, and the second is through Fourier analysis and the concepts of convolution and autocorrelation. This dual treatment bridges the gap between the introductory material in the book and the advanced material in the journals. The book also discusses information theory, Fourier analysis, and mathematical theorems to complete derivations or to give alternate views of an individual subject. The text presents the development of optical theory and equations to the extent required by the advanced student or researcher. The book is intended as a guide for students taking advanced research programs in spectroscopy. Material is included for the physicists, chemists, astronomers, and others who are interested in spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: A real-time system to perform Fourier spectroscopy is described. The spectral distribution is synthesized by the successive summation of cosine functions with amplitudes and frequencies which are determined by the sample points of the interferogram. Summation of these cosine functions is performed in a digital memory oscilloscope which has 1024 addresses. The design criteria and the principles of operation of the system are discussed in detail. Sources of error are examined and several methods of error reduction are discussed. The limitations of this type of system are described and improvements are recommended. Experimental data are presented and the performance of the real-time system is compared to that of a special purpose analog computer, and a digital computer. (Author).
