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).

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.

Download or read book Experimental Mechanics in Nano and Biotechnology written by Soon Bok Lee and published by Trans Tech Publications Ltd. This book was released on 2006-12-01 with total page 1920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume is indexed by Thomson Reuters CPCI-S (WoS). The main focus of this book is the rapidly expanding new field of experimental mechanics, as applied to nano and biotechnology, which is enthusiastically responding to the advances in these technologies and to the increasing need for precise measurements of novel materials and biological tissues. For instance, whereas optical techniques had previously been preferred, particularly in the field of bio-engineering, other mature methods are now being exploited in tandem with the growth in micro- and nano-manufacturing.
Download or read book Transform Techniques in Chemistry written by P. Griffiths and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of the Fourier transform is being seen to an increasing extent in all branches of chemistry, but it is in the area of chemical analysis that the greatest activity is taking place. Fourier transform infrared and nuclear magnetic resonance spectrometry are already routine methods for obtaining high-sensitivity IR and NMR spectra. Analogous methods are now being developed for mass spectrometry (Fourier transform ion cyclo tron resonance spectrometry) and microwave spectroscopy, and Fourier transform techniques have been successfully applied in several areas of electrochemistry. In addition the fast Fourier transform algorithm has been used for smoothing, interpolation, and more efficient storage of data, and has been studied as a potential method for more efficient identification of samples using pattern recognition techniques. Linear transforms have also been shown to be useful in analytical chemistry. Probably the most important of these is the Hadamard transform, which has been applied in alternative methods for obtaining IR and NMR data at high sensitivity. Even though measurements involving this algorithm will probably not be applied as universally as their Fourier transform ana logs, in the area of pattern recognition application of the Hadamard trans form will in all probability prove more important than application of the Fourier transform.
Download or read book Spectroscopy in the Biomedical Sciences written by R.M. Gendreau and published by CRC Press. This book was released on 2018-01-18 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intent of this book a collection of manuscripts - is to provide general descriptions of analytical techniques which we believe to be useful to the biological scientist, and to provide examples of the utility of each technique. The contributing authors were asked to focus on examples in which their particular technique has proven particularly useful in studies of biological systems. Many commonly used analytical techniques such as NMR and ESR are not included in this work, it is preferred to focus on techniques which perhaps have not received as much coverage as in the recent literature. All of the analytical tools covered in this volume have great utility, and the scientific community can expect to see increasing usage of most if not all of these techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Every so often, a reference book appears that stands apart from all others, destined to become the definitive work in its field. The Vibration and Shock Handbook is just such a reference. From its ambitious scope to its impressive list of contributors, this handbook delivers all of the techniques, tools, instrumentation, and data needed to model, analyze, monitor, modify, and control vibration, shock, noise, and acoustics. Providing convenient, thorough, up-to-date, and authoritative coverage, the editor summarizes important and complex concepts and results into “snapshot” windows to make quick access to this critical information even easier. The Handbook’s nine sections encompass: fundamentals and analytical techniques; computer techniques, tools, and signal analysis; shock and vibration methodologies; instrumentation and testing; vibration suppression, damping, and control; monitoring and diagnosis; seismic vibration and related regulatory issues; system design, application, and control implementation; and acoustics and noise suppression. The book also features an extensive glossary and convenient cross-referencing, plus references at the end of each chapter. Brimming with illustrations, equations, examples, and case studies, the Vibration and Shock Handbook is the most extensive, practical, and comprehensive reference in the field. It is a must-have for anyone, beginner or expert, who is serious about investigating and controlling vibration and acoustics.
