Description : With test methodologies and data analysis techniques that apply to all imaging systems and detector array characterizations, including visible, near infrared, short-wavelength infrared (SWIR), mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR), Holst has updated this edition to include current practice of capturing the data with a frame grabber for computer analysis. He also clarifies the concept of target background delta-T and updates chapters on noise and modulation transfer function (MTF) measurements. He covers infrared (IR) imaging system operation, IR technology, general measuring techniques, focus and system resolution, system responsivity, system noise, transfer functions (modulation, phase and contrast, geometric transfer function, observer interpretation of image quality, automated testing and uncertainty analysis. Holst builds from basic material to that which is more advanced, making this a suitable for both self-study and the classroom, and his illustrations are well-chosen.
Description : This book is intended to serve as an introduction to the technology of thermal imaging, and as a compendium of the conventions which form the basis of current FUR practice. Those topics in thermal imaging which are covered adequately elsewhere are not treated here, so there is no discussion of detectors, cryogenic coolers, circuit design, or video displays. Useful infor mation which is not readily available because of obscure publication is referenced as originating from personal communications. Virtually everyone with whom I have worked in the thermal imaging business has contributed to the book through the effects of conversations and ideas. I gratefully proffer blanket appreciation to all those who have helped in that way to make this book possible. The contributions of five people, however, bear special mention: Bob Sendall, Luke Biberman, Pete Laakmann, George Hopper, and Norm Stetson. They, more than any others, have positively influenced my thinking.
Description : This richly illustrated hands-on guide is designed for researchers, teachers and practitioners. The huge selection of examples taken from science, basic teaching of physics, practical applications in industry and a variety of other disciplines spanning the range from medicine to volcano research allows readers to pick those that come closest to their own individual task at hand. Following a look at the fundamentals of IR thermal imaging, properties of the imaging systems, as well as basic and advanced methods, the book goes on to discuss IR imaging applications in teaching, research and industry. Specific examples include thermography of buildings, microsystems and the rather new field of IR imaging of gases. Impartially written by expert authors in the field from a renowned applied science institution, who are in the unique position of having both experience in public and private research and in teaching, this comprehensive book can be used for teaching beginners in the field as well as providing further education to specialized staff, students and researchers.
Description : This is the first book to describe an emerging but already growing technology of thermal imaging based on uncooled infrared imaging arrays and systems, which are the most exciting new developments in infrared technology today. This technology is of great importance to developers and users of thermal images for military and commercial applications. The chapters, prepared by world leaders in the technology, describe not only the mainstream efforts, but also exciting new approaches and fundamental limits applicable to all. Unified approach to technology development based on fundamental limits Individual chapters written by world leaders in each technology Novel potential approaches, allowing for the reduction of costs, described in detail Descriptive and analytical Provides details of the mainstream approaches--resistive bolometric, pyroelectric/field enhanced pyroelectric, thermoelectric Provides insight into a unified approach to development of all types of thermal imaging arrays Features state-of-the-art and selected new developments
Description : The evolution of technological advances in infrared sensor technology, image processing, "smart" algorithms, knowledge-based databases, and their overall system integration has resulted in new methods of research and use in medical infrared imaging. The development of infrared cameras with focal plane arrays no longer requiring cooling, added a new dimension to this modality. Medical Infrared Imaging: Principles and Practices covers new ideas, concepts, and technologies along with historical background and clinical applications. The book begins by exploring worldwide advances in the medical applications of thermal imaging systems. It covers technology and hardware including detectors, detector materials, un-cooled focal plane arrays, high performance systems, camera characterization, electronics for on-chip image processing, optics, and cost-reduction designs. It then discusses the physiological basis of the thermal signature and its interpretation in a medical setting. The book also covers novel and emerging techniques, the complexities and importance of protocols for effective and reproducible results, storage and retrieval of thermal images, and ethical obligations. Of interest to both the medical and biomedical engineering communities, the book explores many opportunities for developing and conducting multidisciplinary research in many areas of medical infrared imaging. These range from clinical quantification to intelligent image processing for enhancement of the interpretation of images, and for further development of user-friendly high-resolution thermal cameras. These would enable the wide use of infrared imaging as a viable, noninvasive, low-cost, first-line detection modality.
Description : This introduction to uncooled infrared focal plane arrays and their applications is aimed at professionals, students, and end users. Topics include principal uncooled thermal detection mechanisms; fundamental performance limits and theoretical performance; the state of the art; and applications, technical trends, and systems employing uncooled arrays.
