Book Description
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

Book Description
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.

Book Description
The National Institute of Standards and Technology supplies calibrated photodiode standards and special tests of photodetectors for absolute spectral responsivity from 200 nm to 1800 nm. (This service will soon be expanded to 20 μm in the infrared.) The scale of absolute spectral responsivity is based solely on detector measurements traceable to the High Accuracy Cryogenic Radiometer maintained by the National Institute of Standards and Technology. Silicon photodiode light-trapping detectors are used to transfer the optical power unit from this cryogenic radiometer to monochromator-based facilities where routine measurements are performed. The transfer also involves modeling the quantum efficiency of the silicon photodiode light-trapping detectors. A description of current measurement services is given along with the procedures, equipment, and techniques used to perform these calibrations. Detailed estimates and procedures for determining uncertainties of the reported values are also presented.

Book Description
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
