"Radiometry is a fascinating, fast growing research area, and there are many interesting real life applications. This book is intended to provide readers the theoretical background of radiometry, a resource of the latest radiometry technology, as well as the latest research in radiometry. It is aimed at university/college students, researchers and engineers. It assumes readers have basic knowledge and skills concerning electronics, physics and mathematics at the university level. This book is divided into three parts. Part I is the Introduction to Radiometry, which includes the theoretical background of radiometry, radiometry sources, radiometry detectors, and radiometry optical systems. This part also includes the latest technologies available, such as different Quantum Cascade Lasers, wavelength tuneable detectors, thermal electric cooled and Stirling cooled detectors, multispectral and hyperspectral thermal cameras, high resolution and high speed thermal cameras, and various radiometry optical detection systems. Part II is called the Advances in Radiometry Research, which contains the development of the latest research in areas of biomedical applications, industrial applications, non-destructive testing, astronomy and environmental applications. This is the core part of the book, and provides a review of the latest research trends in radiometry in different application areas"-- Provided by publisher.
