Excerpt from Self-Study Manual on Optical Radiation Measurements, Vol. 3: Applications, Chapter 1; Measurement of Solar Terrestrial Spectral Irradiance in the Ozone Cut-Off Region
Preparation of the nbs self-study Manual on Optical Radiation Measurements is an important part of our effort to meet the needs of the National Measurement System with respect to the measurement of optical electromagnetic radiation. Significant needs exist for measurements with uncertainties of about one percent, but the uncertainties actually achieved are often 5 to 10 percent, or even more. These relatively poor accuracies, as compared to those in many other types of physical measurements, result to a great extent from the multidimensional character of optical radiation; radiant energy is dis tributed and may vary with position, direction, wavelength, polarization, and time. Measurement results are also affected by various instrumental and environmental parameters. In addition, many of those who make measurements of optical radiation have little or no training or experience in this field and are limited in the amount of time they can devote to acquiring the needed information, understanding, and proficiency with measurement techniques. Moreover, there are few schools that offer courses in radiometry, and there are almost no adequate texts or references dealing with this entire subject.

Paperback. Zustand: New. Print on Demand. This book is a tutorial manual on optical radiation measurements, providing comprehensive detailed treatments that are complete enough for self-instruction without requiring programmed learning steps. The material presented in the book is maintained at a college graduate level in science or engineering and is written with the assumption that readers are familiar with a first course in physics and college mathematics. The focus of this book is on the measurement equation, which is used to determine the quantity of optical radiation desired and relate it to the data obtained. An overview of the basic material of Part I â" Concepts is provided, which is structured to build the measurement equation step-by-step in terms of the radiation parameters, the properties and characteristics of sources, optical paths, and receivers, and the environmental and instrumental parameters. The parameters addressed include position, direction, spectrum, time or frequency of modulation or fluctuation, and polarization. The book also contains discussions on relevant quantities and their applications in various fields such as photometry, heat transfer engineering, astronomy, and photobiology. The insights of this book are significant for enhancing the accuracy of optical radiation measurements, a notable challenge in the field. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9781528224758_0
