Radiometric Calibration: Theory and Methods contains an engineering development of the theories and methods of radiometric calibration. This book is organized into 18 chapters. Chapters I to V present an introduction to nomenclature, radiation geometry, and blackbody radiation that serves to simplify the discussion of the calibration theory. The rest of the chapters provide the theory of sensor calibration, reviewing numerous examples in which laboratory equipment and specific techniques are described. Algorithms are also covered for digital computer processing as appropriate for each functional aspect of sensor characterization. This publication is intended for engineers and applied physicists concerned with sensor calibration and the interpretation of sensor data.

This book deals with the practice of Optical Radiation Measurements with introductory material to introduce the topics discussed. It will be most useful for students, scientists and engineers working in any academic, industrial or governmental projects related to optical radiation. The book contains chapters that treat in detail the procedures and techniques for the characterization of both sources and detectors to the highest degree of accuracy and reliability. It has a chapter devoted specifically to optical measurements of laser sources and fiberoptics for communication and a chapter devoted to uncertainty in measurement and its treatment with real examples of optical measurements. The book contains introductory materials that will allow a newcomer to radiometry to develop the expertise to perform exacting and accurate measurement. The authors stress the various causes of uncertainty in each phase of a measurement and thus allow for users to arrive at a correct assessment of their uncertainty of measurement in their particular circumstance. · Authors are from the Standards laboratories of AUSTRALIA, CANADA, ENGLAND, GERMANY and the USA. · Latest techniques and practice of laboratory measurements to achieve the highest accuracy in the use of sources or detectors. · Unique illustrations of the apparatus and measurement techniques. · Practical measurement examples of calibration with full uncertainty analysis. · Comprehensive treatment of optical standards such as sources, detectors and radiometers. · A complete chapter on laser power measurements and standards for fiber optic measurements · A complete chapter on correlations in radiometry and practical examples. · A chapter devoted to diffraction effects in radiometry

This document describes the selection of a laboratory-based, spectroradiometric standard to provide for the calibration of the near-infrared instrumentation of the Remote Sensing Department of the Space Sciences Application Laboratory. The goal is to provide a source whose spectral emittance is known to better than 1% over the entire near-infrared spectral region (0.8-2.5 mironm) and which can be calibrated directly at the National Institute of Standards (NIST). The source selected is a freeze-point cavity blackbody that uses a copper melt with a temperature of 1084.62C and provides an on-axis effective emissivity of> 0.999. The nominal temperature uncertainty provided by the vendor is +/-O.5C, sufficient to meet our specification. However, through the calibration (and certification) by NIST, the intent is to reduce this value to

This book describes the theory of radiation thermometry, both at a primary level and for a variety of applications, such as in the materials processing industries and remote sensing. This book is written for those who will apply radiation thermometry in industrial practice; use radiation thermometers for scientific research; the radiation thermometry specialist in a national measurement institute; developers of radiation thermometers who are working to innovate products for instrument manufacturers, and developers of non-contact thermometry methods to address challenging thermometry problems. The authors of each chapter were chosen from a group of international scientists who are experts in the field and specialists on the subject matter covered in the chapter. A large number of references are included at the end of each chapter as a resource for those seeking a deeper or more detailed understanding. This book is more than a practice guide, readers will gain in-depth knowledge in: (1) the proper selection of the type of thermometer; (2) the best practice in using the radiation thermometers; (3) awareness of the error sources and subsequent appropriate procedure to reduce the overall uncertainty; and (4) understanding of the calibration chain and its current limitations. Covers all fundamental aspects of the radiometric measurements Discusses practical applications with details on the instrumentation, calibration, and error sources Authors are from leading national labs working in R&D of temperature measurements
