Spectroscopy is a powerful technique that utilizes the interaction of light with matter. Analysis of various spectra can yield important physical characteristics of matter, including chemical composition, temperature, luminosity, mass, and more. The uses and implications of spectroscopy are very broad, with practical uses in many fields of science, including astronomy, medicine, analytic chemistry, material science, geology, and more. Researchers are constantly discovering new applications of spectroscopy, and it is expected to play an ever-increasing role in nanotechnology and superconductivity. This book brings together a diverse collection of new research advances in spectroscopy.

Terahertz imaging looks set to become an integral part of future applications from semiconductor quality control to medical diagnosis. This will only become a reality when the technology is sufficiently cheap and capabilities adequate to compete with others. Single-pixel cameras use a spatial light modulator and a detector with no spatial-resolution in their imaging process. The spatial-modulator is key as it imparts a series of encoding masks on the beam and the detector measures the dot product of each mask and the object, thereby allowing computers to recover an image via post-processing. They are inherently slower than parallel-pixel imaging arrays although they are more robust and cheaper, hence are highly applicable to the terahertz regime. This chapter dedicates itself to terahertz single-pixel cameras; their current implementations, future directions and how they compare to other terahertz imaging techniques. We start by outlining the competing imaging techniques, then we discuss the theory behind single-pixel imaging; the main section shows the methods of spatially modulating a terahertz beam; and finally there is a discussion about the future limits of such cameras and the concluding remarks express the authors' vision for the future of single-pixel THz cameras.

An invaluable text for the teaching, design, and development of gas sensor technology. This excellent resource synthesizes the fundamental principles of spectroscopy, laser physics, and photonics technology and engineering to enable the reader to fully understand the key issues and apply them in the design of optical gas absorption sensors. It provides a straightforward introduction to low-cost and highly versatile near-IR systems, as well as an extensive review of mid-IR systems. Fibre laser systems for spectroscopy are also examined in detail, especially the emerging technique of frequency comb spectroscopy. Featuring many examples of real-world application and performance, as well as MATLAB computer programs for modeling and simulation, this exceptional work is ideal for postgraduate students, researchers, and professional engineers seeking to gain an in-depth understanding of the principles and applications of fibre-optic and laser-based gas sensors.

Though the use of various spectroscopic methods and sensor technology is routine in water quality evaluation. Coupled with artificial intelligence, machine learning, and deep learning methods are opening a new era of quality monitoring and predictive analysis. This book acquaints experienced readers with recent advances and how these techniques are finding applications in water analysis for sectors including environmental protection, industry, agriculture, and drinking water provision. Taking a bottom-up approach the work is also suited for an interdisciplinary readership who may not have direct experience in a particular technique. Qualitative and quantitative analysis of data with the help of observed data is included, as are case studies. Part of IOP Series in Spectroscopic Methods and Applications.

This volume presents methods used for the analysis of glycoproteins at different levels—intact, subunit, glycopeptide, and monosaccharide--, and discusses and solves most analytical challenges that a scientist working on glycoproteins may come across. The chapters in this book cover topics such as the role of glycosylation on the properties of therapeutic glycoproteins; different analytical methods to characterize glycosylation, from the intact proteins to the glycan level, for both N-linked and O-linked glycoproteins; mass spectrometry imaging methodology for glycosylation analysis in tissues; approaches to characterizing glycosylation on cultured cells; and the use of cloud computing to deploy mass spectrometry data analysis. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Mass Spectrometry of Glycoproteins: Methods and Protocols is a valuable resource for scientists interested in learning more about this developing field.
