The book includes fundamental concepts of theory, instrumentation, and experimental practice as well as practical applications. An important chapter setting the book apart from other publications describes the properties of materials and presents case studies from industry. In addition, a program called IRNDT accompanies the book and is available on the Wiley ftp site. The program includes an image bank that can be used to test the principles covered in the book. * All chapters end with summaries, problems, and questions. * Authored by an acknowledged expert in the field. * Material draws on case studies to illustrate major points.

Imagine an analytical technique that uses no chemicals, gives accurate and precise results in minutes or even continuously, and is simple to install and safe to use. Near-infrared spectroscopy (NIRS) supplies this dream. This book covers all of the essential features for successful NIRS application in a practical and easily understandable format. The driving force behind compiling this book is to provide knowledge on all aspects of NIRS to potential users, and to users who would like to delve a little deeper into the technology. We have assembled the book, mainly to help in the application of near-infrared (NIR) instruments and technology in industry.

In Infrared Thermography, the authors discuss the sources of uncertainty, including how to quantify these sources, associated with the use of thermal imagers. This book explains the common misunderstandings in the interpretation of temperature measurements, and provides a metrological evaluation of commercially available infrared cameras. It suggests how to best estimate the accuracy of thermal imaging instruments, whilst considering the level of accuracy attributed to measurements from these thermal imagers. Key features: Begins with an introduction to uncertainties and radiance terms before moving onto the issues surrounding thermal imaging. Deals with the basic issues of thermal imager measurements such as the law of heat exchange by radiation and emissivity. Describes a typical processing algorithm of the measurement path for an example infrared camera. Discusses measurement error analysis of a thermal imaging system. Considers the results of simulation research of thermography uncertainty. Includes an accompanying website which hosts MATLAB® code. Infrared Thermography is primarily aimed at quantitative thermographers, and manufacturers, vendors and users of thermal imagers. This book is also of interest to senior undergraduate and postgraduate students across a range of disciplines such as electrical, mechanical and civil engineering, computer science, and biomedicine.
