"Revealing the fundamentals of light beam deflection control, factors in image fidelity and quality, and the newest technological developments currently impacting scanner system design and applications, this highly practical reference reviews elements of laser beam characterization and describes optical systems for laser scanners. Featuring a logical chapter organization, authoritative yet accessible writing, hundreds of supporting illustrations, and contributions from 27 international subject specialists, this book affords a valuable range of perspectives as well as global coverage of optical and laser beam scanning. "-- Provided by publisher. "Preface Optical and laser scanning is the controlled deflection of light, visible or invisible. The aim of Handbook of Optical and Laser Scanning is to provide engineers, scientists, managerial technologists, and students with a resource to be used as a reference for understanding the fundamentals of optical scanning technology. This text has evolved from three previous books, Laser Beam Scanning (1985), Optical Scanning (1991), and Handbook of Optical and Laser Scanning (2004). Since their publication, many advances have occurred in optical scanning, requiring updating of previous material and introduction of additional scanning technologies. This new edition also adds a few chapters on scanning applications illustrating the practical use of scanning technology. Optical and laser scanning is a topic that is extremely broad in scope. It encompasses the mechanisms that control the deflection of light, optical systems that work with these mechanisms to perform scanning functions and factors that affect the fidelity of the images generated or obtained from the scanning systems. Each of these subtopics is addressed in this book from a variety of perspectives. A scanning system can be an input or output system or a combination of both. Input systems acquire images in either two or three dimensions. These systems can operate at a fixed wavelength or over a broad spectrum. They can reacquire the original light source by gathering either the specular or diffuse reflection or by fluorescing the image and acquiring the fluoresced light. Output systems direct light to produce images for applications such as marking, visual projection, and hard copy output. Ladar and many inspection systems use the same optical path to both illuminate the scene and acquire the image"-- Provided by publisher.

3D scanning is a process that captures the three-dimensional attributes of an object and includes surface texture and spectral content. 3D scanners have become a critical tool for shortening product development and manufacturing time. The ongoing technological advancements in terms of portability, scanning range, and image quality have opened new application areas for 3D scanning. However, 3D scanning appears to be primarily dependent on users. Innovation in technology and application software, as well as growing and diverse connectivity, are leading 3D scanners to become a more integral element in the overall value chain. This notwithstanding, interoperability, data security and privacy, quality, portability, and trustworthiness are opportunities to be realized. The intent of this white paper is to highlight areas of opportunity for standard development organizations, specifically the IEEE P3141 Working Group, to focus on and further enable broad market use for the various sectors and users.

Using Scanner Data for Food Policy Research is a practitioners' guide to using and interpreting scanner data obtained from stores and households in policy research. It provides practical advice for using the data and interpreting their results. It helps the reader address key methodological issues such as aggregation, constructing price indices, and matching the data to nutrient values. It demonstrates some of the key econometric and statistical applications of the data, including estimating demand systems for policy simulation, analyzing effects of food access on food choices, and conducting cost-benefit analysis of food policies. This guide is intended for early-career researchers, particularly those working with scanner data in agricultural and food economics, nutrition, and public health contexts. --
