This book discusses modern, user-friendly radiometric practices that make it possible to convert from traditional source-based optical radiation measurements to the more efficient and higher accuracy detector-based applications and calibrations. It considers improved performance optical detector and radiometer standards including photometers and tristimulus colorimeters, and describes research-based design considerations, measurement of radiometric, optical, and electronic characteristics, and comparison of absolute-, transfer-, and working-standard detectors and radiometers from the ultraviolet (UV) to the infrared (IR) range. The book will serve to guide the optical radiation measurement community, researchers, manufacturers, calibration laboratories, students, and practicing engineers to switch from the old and limited-use measurement methods to the higher performance detector-based applications. The radiometer standards discussed here can be used to produce wide range radiometric, photometric, colour, and radiation temperature measurements with low uncertainty.

The recently developed optical radiation detectors need well-designed radiometers to perform improved radiometric, photometric, colorimetric, and radiation-temperature measurements. They can produce higher performance than traditionally used blackbody sources and lamps in wider application areas. This book presents research-based material in this field that has been implemented, realized, tested, verified, and evaluated. It can be used as a reference source for students, practicing scientists, engineers, technicians, instrument manufacturers and measurement/calibration people to learn, design, build, select, and use new generation radiometers. The book describes a number of design issues and applications to implement the correct input geometry for detectors to measure radiometric (power, irradiance and radiance) quantities, and DC, AC, and pulsed electrical output signals.

This is the first book to investigate the improved performance of optical radiation detectors developed from the ultraviolet to the far-infrared in the past two decades. The development and applications of these improved detectors opened up a new era in radiometric, photometric, colorimetric, and radiation-temperature measurements where earlier blackbody sources and lamps were used with lower performance and in limited application areas. This book will serve to help students, practicing scientists, engineers, technicians, and instrument manufacturers to learn, compare and select the proper detectors for building, using, and calibrating opto-electronic instruments with SI traceability and lowered measurement uncertainty in extended application areas.

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

In most field applications, broadband measurements are used where the spectral product of the source distribution and the meter’s spectral responsivity is measured. This book discusses detector-based radiometric, photometric, color, radiation-temperature, digital imaging-system, and LED measurements. It also shows that, while in photometry, the meter’s standard response covers only the visible, broadband measurements in the UV and IR require different standards. To avoid large errors when using a traditional detector- or source-standard, where the differences in the source distributions and in the meter’s responsivities produce large errors, the signal measurement procedure itself must be standardized. To satisfy the steps of the procedure, selected or properly designed meters should be used. This book is a guide to performing uniform broadband measurements with low uncertainty.

Established by Congress in 1901, the National Bureau of Standards (NBS), now the National Institute of Standards and Technology (NIST), has a long and distinguished history as the custodian and disseminator of the United States' standards of physical measurement. Having reached its centennial anniversary, the NBS/NIST reflects on and celebrates its first century with this book describing some of its seminal contributions to science and technology. Within these pages are 102 vignettes that describe some of the Institute's classic publications. Each vignette relates the context in which the publication appeared, its impact on science, technology, and the general public, and brief details about the lives and work of the authors. The groundbreaking works depicted include: A breakthrough paper on laser-cooling of atoms below the Doppler limit, which led to the award of the 1997 Nobel Prize for Physics to William D. Phillips The official report on the development of the radio proximity fuse, one of the most important new weapons of World War II The 1932 paper reporting the discovery of deuterium in experiments that led to Harold Urey's1934 Nobel Prize for Chemistry A review of the development of the SEAC, the first digital computer to employ stored programs and the first to process images in digital form The first paper demonstrating that parity is not conserved in nuclear physics, a result that shattered a fundamental concept of theoretical physics and led to a Nobel Prize for T. D. Lee and C. Y. Yang "Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor," a 1995 paper that has already opened vast new areas of research A landmark contribution to the field of protein crystallography by Wlodawer and coworkers on the use of joint x-ray and neutron diffraction to determine the structure of proteins

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.
