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.

Download or read book Thermal and Electro thermal System Simulation 2020 written by Márta Rencz and published by MDPI. This book was released on 2021-01-12 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, edited by Prof. Marta Rencz and Prof Andras Poppe, Budapest University of Technology and Economics, and by Prof. Lorenzo Codecasa, Politecnico di Milano, collects fourteen papers carefully selected for the “thermal and electro-thermal system simulation” Special Issue of Energies. These contributions present the latest results in a currently very “hot” topic in electronics: the thermal and electro-thermal simulation of electronic components and systems. Several papers here proposed have turned out to be extended versions of papers presented at THERMINIC 2019, which was one of the 2019 stages of choice for presenting outstanding contributions on thermal and electro-thermal simulation of electronic systems. The papers proposed to the thermal community in this book deal with modeling and simulation of state-of-the-art applications which are highly critical from the thermal point of view, and around which there is great research activity in both industry and academia. In particular, contributions are proposed on the multi-physics simulation of families of electronic packages, multi-physics advanced modeling in power electronics, multiphysics modeling and simulation of LEDs, batteries and other micro and nano-structures.

Download or read book Digital Color Imaging Handbook written by Gaurav Sharma and published by CRC Press. This book was released on 2017-12-19 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital technology now enables unparalleled functionality and flexibility in the capture, processing, exchange, and output of color images. But harnessing its potential requires knowledge of color science, systems, processing algorithms, and device characteristics-topics drawn from a broad range of disciplines. One can acquire the requisite background with an armload of physics, chemistry, engineering, computer science, and mathematics books and journals- or one can find it here, in the Digital Color Imaging Handbook. Unprecedented in scope, this handbook presents, in a single concise and authoritative publication, the elements of these diverse areas relevant to digital color imaging. The first three chapters cover the basics of color vision, perception, and physics that underpin digital color imaging. The remainder of the text presents the technology of color imaging with chapters on color management, device color characterization, digital halftoning, image compression, color quantization, gamut mapping, computationally efficient transform algorithms, and color image processing for digital cameras. Each chapter is written by world-class experts and largely self-contained, but cross references between chapters reflect the topics' important interrelations. Supplemental materials are available for download from the CRC Web site, including electronic versions of some of the images presented in the book.

Download or read book The Measurement of Appearance written by Richard S. Hunter and published by John Wiley & Sons. This book was released on 1987-09-08 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of a unique text/reference identifies the appearance attributes of objects and the methods available for measuring them, bringing together much material not previously organized for ready reference. The primary premise here is that ``object appearance'' involves not only color, but such attributes as gloss, luster, and translucency. The first part of the book, concerned with nature of appearance, draws from the fields of physiology and psychology and considers the eye-brain combination and the way it receives and interprets light signals. This is followed by a consideration of the optical properties of objects from the physical standpoint. The second part of the book deals with the numerical scales used to measure object appearance. The discussion here draws on psychophysics in describing the uses of physical techniques to give numbers having psychological significance. The third part of the book covers instruments for the measurement of the attributes of object appearance, their principles of design, and a survey of the major ones in use. The final chapter discusses specific applications of appearance measurement. Includes appendixes and a glossary.
