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.
The revised 2nd edition of this practical book provides an expanded treatment and comparison of techniques used in advanced optical measurements, guiding its reader from fundamental radiometric and photometric concepts to the state-of-the-art in highly sensitive measurements of optical losses and in spectroscopic detection using coherent laser light and spontaneous radiation. The book describes and compares a broad array of high-sensitivity methods and techniques – from interferometric and/or calorimetric, acousto-optic and resonator or polarization to wavelength- and frequency-modulation, phase-shift and decay time studies, and direct-loss measurements for free-space, fiber- or waveguide-based systems and devices. Updated throughout, the new edition describes novel trends in spectral interferometry, frequency-comb and laser-excitation spectroscopy, reflected in the developments of Raman, Brillouin and FTIR (Fourier Transform Infra-Red) techniques for biomedical research, biotech sensing and detection. It also covers broad practical implementations of time- and frequency-domain terahertz spectroscopy measurements.

This book presents an overview of both the theory and experimental methods required to realize high efficiency solar absorber devices. It begins with a historical description of the study of spectrally selective solar absorber materials and structures based on optical principles and methods developed over the past few decades. The optical properties of metals and dielectric materials are addressed to provide the background necessary to achieve high performance of the solar absorber devices as applied in the solar energy field. In the following sections, different types of materials and structures, together with the relevant experimental methods, are discussed for practical construction and fabrication of the solar absorber devices, aiming to maximally harvest the solar energy while at the same time effectively suppressing the heat-emission loss. The optical principles and methods used to evaluate the performance of solar absorber devices with broad applications in different physical conditions are presented. The book is suitable for graduate students in applied physics, and provides a valuable reference for researchers working actively in the field of solar energy.
This new resource provides an insight into the physical principles of the device technology that underpins many laser-based military systems in one form or another. From this knowledge a deeper understanding of the fundamental requirements and the potential performance, as well as limitations of such systems may be assessed, given the appropriate operational parameters. Engineers and students are provided with practical advice on how to evaluate laser devices and systems, operate them safely, and train with them.
This accessible handbook demonstrates how reflected light can be measured and used to investigate the properties of Solar System objects.
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.
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.
