This book was released on 2020-12-01 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2020-10-27 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Eppeldauer and published by Forgotten Books. This book was released on 2017-10-28 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Optical Radiation Measurement With Selected Detectors and Matched Electronic Circuits Between 200 Nm and 20 Μm Improved detector technology in the past decade opened a new era in the field of radiometric and photometric calibrations. Now, cryogenic electrical substitution radiometers with optical power measurement uncertainty are the primary standards of the field. New generation radiometers, built with high electronic and radiometric performance detectors, became the transfer and working standards to propagate the high accuracy from the primary standard to field level measurements. The importance of high quality detector standards has greatly increased as a result of demands in a wide range of technical areas. Nowadays, lamp standards, traditionally calibrated against source standards, are calibrated against detector standards to obtain improved calibration accuracy.

Book excerpt: 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.

Download or read book Spectroradiometric Detector Measurements written by Thomas C. Larason and published by Createspace Independent Publishing Platform. This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods and Materials for Remote Sensing: Infrared Photo-Detectors, Radiometers and Arrays presents the basic principles and the guidelines for the design of IR and microwave radiometers intended for the detection of weak electromagnetic signals in a noisy background. Significant attention is paid in this book to the discussion of the origin of the noises and consideration of the physical factors limiting the sensitivity of photo sensors. The physico-chemical properties of narrow-band semiconductors, which are the basic photosensitive materials for the microwave and IR radiometry, are discussed. Also described are the methods for growing the single crystals, epitaxial films and arrays from solid solutions of these compounds for the application in photosensitive detectors. The main goal of Methods and Materials for Remote Sensing: Infrared Photo-Detectors, Radiometers and Arrays is to present the entire material from the unifying physical viewpoint, which will be helpful for the designers of photo-detecting devices, and professionals contributing in various areas of remote sensing.
Download or read book Broadband UV VIS and IR Radiometric Photometric Color and Temperature Measurements written by George P. Eppeldauer and published by Cambridge Scholars Publishing. This book was released on 2021-04-07 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
