Book Description
Applied Photometry, Radiometry, and Measurements of Optical Losses reviews and analyzes physical concepts of radiation transfer, providing quantitative foundation for the means of measurements of optical losses, which affect propagation and distribution of light waves in various media and in diverse optical systems and components. The comprehensive analysis of advanced methodologies for low-loss detection is outlined in comparison with the classic photometric and radiometric observations, having a broad range of techniques examined and summarized: from interferometric and calorimetric, resonator and polarization, phase-shift and ring-down decay, wavelength and frequency modulation to pulse separation and resonant, acousto-optic and emissive - subsequently compared to direct and balancing methods for studying free-space and polarization optics, fibers and waveguides. The material is focused on applying optical methods and procedures for evaluation of transparent, reflecting, scattering, absorbing, and aggregated objects, and for determination of power and energy parameters of radiation and color properties of light.

Book Description
LED Lighting is a self-contained and introductory-level book featuring a blend of theory and applications that thoroughly covers this important interdisciplinary area. Building on the underlying fields of optics, photonics, and vision science, it comprises four parts. PART I is devoted to fundamentals. The behavior of light is described in terms of rays, waves, and photons. Each of these approaches is best suited to a particular set of applications. The properties of blackbody radiation, thermal light, and incandescent light are derived and explained. The essentials of semiconductor physics are set forth, including the operation of junctions and heterojunctions, quantum wells and quantum dots, and organic and perovskite semiconductors. PART II deals with the generation of light in semiconductors, and details the operation and properties of III-V semiconductor devices (MQWLEDs and μLEDs), quantum-dot devices (QLEDs & WOLEDs), organic semiconductor devices (OLEDs, SMOLEDs, PLEDs, & WOLEDs), and perovskite devices (PeLEDs, PPeLEDs, QPeLEDs, & PeWLEDs). PART III focuses on vision and the perception of color, as well as on colorimetry. It delineates radiometric and photometric quantities as well as efficacy and efficiency measures. It relays the significance of metrics often encountered in LED lighting, including the color rendering index (CRI), color temperature (CT), correlated color temperature (CCT), and chromaticity diagram. PART IV is devoted to LED lighting, focusing on its history and salutary features, and on how this modern form of illumination is deployed. It describes the principal components used in LED lighting, including white phosphor-conversion LEDs, chip-on-board (COB) devices, color-mixing LEDs, hybrid devices, LED filaments, retrofit LED lamps, LED luminaires, and OLED light panels. It concludes with a discussion of smart lighting and connected lighting. Each chapter contains highlighted equations, color-coded figures, practical examples, and reading lists.

Book Description
Shelving Guide: Electrical Engineering In 1900 the great German theoretical physicist Max Planck formulated a correct mathematical description of blackbody radiation. Today, understanding the behavior of a blackbody is of importance to many fields including thermal and infrared systems engineering, pyrometry, astronomy, meteorology, and illumination. This book gives an account of the development of Planck’s equation together with many of the other functions closely related to it. Particular attention is paid to the computational aspects employed in the evaluation of these functions together with the various aids developed to facilitate such calculations. The book is divided into three sections. Section I – Thermal radiation and the blackbody problem are introduced and discussed. Early developments made by experimentalists and theoreticians are examined as they strove to understand the problem of the blackbody. Section II – The development of Planck’s equation is explained as are the all-important fractional functions of the first and second kinds which result when Planck’s equation is integrated between finite limits. A number of theoretical developments are discussed that stem directly from Planck’s law, as are the various computational matters that arise when numerical evaluation is required. Basic elements of radiometry that tie together and use many of the theoretical and computational ideas developed is also presented. Section III – A comprehensive account of the various computational aids such as tables, nomograms, graphs, and radiation slide rules devised and used by generations of scientists and engineers when working with blackbody radiation are presented as are more recent aids utilizing computers and digital devices for real-time computations. Scientists and engineers working in fields utilizing blackbody sources will find this book to be a valuable guide in understanding many of the computational aspects and nuances associated with Planck’s equation and its other closely related functions. With over 700 references, it provides an excellent research resource.

Book Description
This second edition of the fully revised and updated From Photon to Pixel presents essential elements in modern digital photographic devices. Our universal infatuation with photography profoundly affects its usage and development. While some sides of photographic “culture” remain wholly unchanged – art photography, journalistic and advertising photography, scientific photography, etc. – new facets emerge: leisure or travel photography, everyday life photography, anecdotal, observational or unusual photography, and microcosm, or micro-community, photography with its culmination in the narcissistic selfie. These new forms combine an often simplified manner of photographing and modern means of instantaneous, remote and mass communication. This book does not extend into the sociological study of photography, instead it explains how the digital camera works by examining in detail each of the components that constitutes it to provide the reader with a preliminary guide into the inner workings of this device.

Book Description
This informative volume reflects the state of art in the science of color-changeable materials and provides an abundance of in-depth knowledge about the field of colorimetry. The book describes the facts behind the chromic phenomena from the point of application, spectrophotometry of chromic materials, and instrumentation and testing. The authors begin with a short historical overview of the chromic phenomena, chromic materials, and classification of chromic materials and then go on to provide comprehensive treatises on chromic (or color-changeable) textiles and production techniques. Detailed descriptions of measurement methods that are usable in cases of translucent or opaque materials are provided as well. A number of new concepts are discussed along with standardized CIE (International Commission on Illumination) colorimetry with various CIE color space systems. Chromic materials appear as a dynamic system, which allows for a wide range of potential applications and related research. The authors share their own experiences with measurement of color chromic materials with the view to help fill the huge gap in field of measurement from the point of view in standardization. The authors conclude with an in-depth study of the testing of chromic testing, including testing for color fastness, fatigue resistance, light fastness, wash fastness, and rubbing fastness.

Book Description
This textbook provides a basic understanding of the principles of the field of organic electronics, through to their applications in organic devices. Useful for both students and practitioners, it is a teaching text as well as an invaluable resource that serves as a jumping-off point for those interested in learning, working and innovating in this rapidly growing field. Organics serve as a platform for very low cost and high performance optoelectronic and electronic devices that cover large areas, are lightweight, and can be both flexible and conformable to fit onto irregularly shaped surfaces such as foldable smart phones. Organic electronics is at the core of the global organic light emitting device (OLED) display industry. OLEDs also have potential uses as lighting sources. Other emerging organic electronic applications include organic solar cells, and organic thin film transistors useful in medical and a range of other sensing, memory and logic applications. This book is a product of both one and two semester courses that have been taught over a period of more than two decades. It is divided into two sections. Part I, Foundations, lays down the fundamental principles of the field of organic electronics. It is assumed that the reader has an elementary knowledge of quantum mechanics, and electricity and magnetism. A background knowledge of organic chemistry is not required. Part II, Applications, focuses on organic electronic devices. It begins with a discussion of organic thin film deposition and patterning, followed by chapters on organic light emitters, detectors, and thin film transistors. The last chapter describes several devices and phenomena that are not covered in the previous chapters, since they lie somewhat outside of the current mainstream of the field, but are nevertheless important.
