Book Description
This book, the first of a two-volume set, focuses on the basic physical principles of blackbody radiometry and describes artificial sources of blackbody radiation, widely used as sources of optical radiation, whose energy characteristics can be calculated on the base of fundamental physical laws. Following a review of radiometric quantities, radiation laws, and radiative heat transfer, it introduces the basic principles of blackbody radiators design, details of their practical implementation, and methods of measuring their defining characteristics, as well as metrological aspects of blackbody-based measurements. Chapters are dedicated to the effective emissivity concept, methods of increasing effective emissivities, their measurement and modeling using the Monte Carlo method, techniques of blackbody radiators heating, cooling, isothermalization, and measuring their temperature. An extensive and comprehensive reference source, this book is of considerable value to students, researchers, and engineers involved in any aspect of blackbody radiometry.

Book Description
Shelving Guide: Electrical Engineering In 1900 the great German theoretical physicist Max Planck formulated a correct mathematical description of blackbody radiation. Today, understanding the behavior of a blackbody is of importance to many fields including thermal and infrared systems engineering, pyrometry, astronomy, meteorology, and illumination. This book gives an account of the development of Planck’s equation together with many of the other functions closely related to it. Particular attention is paid to the computational aspects employed in the evaluation of these functions together with the various aids developed to facilitate such calculations. The book is divided into three sections. Section I – Thermal radiation and the blackbody problem are introduced and discussed. Early developments made by experimentalists and theoreticians are examined as they strove to understand the problem of the blackbody. Section II – The development of Planck’s equation is explained as are the all-important fractional functions of the first and second kinds which result when Planck’s equation is integrated between finite limits. A number of theoretical developments are discussed that stem directly from Planck’s law, as are the various computational matters that arise when numerical evaluation is required. Basic elements of radiometry that tie together and use many of the theoretical and computational ideas developed is also presented. Section III – A comprehensive account of the various computational aids such as tables, nomograms, graphs, and radiation slide rules devised and used by generations of scientists and engineers when working with blackbody radiation are presented as are more recent aids utilizing computers and digital devices for real-time computations. Scientists and engineers working in fields utilizing blackbody sources will find this book to be a valuable guide in understanding many of the computational aspects and nuances associated with Planck’s equation and its other closely related functions. With over 700 references, it provides an excellent research resource.

Book Description
Optical Radiation Measurements, Volume 1: Radiometry is an introduction to the measurement of optical radiant energy, with emphasis on the principles and generally applicable methods of radiometry. Topics range from basic concepts of radiant energy and its transfer to the calibration of instrumentation. Blackbody radiation and sources of radiation are also discussed, along with detectors and spectral analyzers. Comprised of 10 chapters, this volume begins with an overview of the basic concepts and characteristics of radiometry as well as its applications such as photometry, photography, television, and vision research. The next chapters describe basic concepts such as radiation laws, terminology, and the transfer of radiant energy. The emphasis in these early chapters is on fundamentals. The major components of radiometric systems are then considered. The final three chapters focus on representative techniques, with particular reference to measurements of radiant power and radiant energy; reflectance, transmittance, and absorptance; and standards and calibration. This book is written for students, practitioners, and researchers in physics.

Book Description
Absolute Radiometry: Electrically Calibrated Thermal Detectors of Optical Radiation considers the application of absolute radiometry, a technique employed in optical radiation metrology for the absolute measurement of radiant power. This book is composed of eight chapters and begins with the principles of the absolute measurement of radiant power. The subsequent chapters provide the criteria associated with reflectance and transmittance of optical radiation and the parameters used to characterize the performance of radiation detectors. A chapter presents an analysis of the temperature distribution in a detector element. This topic is followed by discussions of the environmental and instrumental corrections in absolute radiometry. The final chapters deal with the alternative optical power scales and direct current substitution methods used in other fields of metrology.
