This book proposal for the “instrumentation & measurement” collection of ISTE-Wiley is devoted to special techniques in digital holography. The co-authors aim at establishing a synthetic stat-of-the-art of important advances in the field of digital holography. We are interested in detailing advances related to fundamentals of digital holography, in-line holography applied to fluid mechanics, digital color holography, digital holographic microscopy, infrared holography, special techniques in full field vibrometry and inverse problems in digital holography. This book presents advanced techniques in the field of digital holography. The book is organized in 8 chapters. The fist chapter introduces the basic fundamentals of digital holography. Chapter 2 discusses about the use of in-line holography to the study of seeded flows; the recent developments permit to apply this technique in many industrial or laboratory situations for velocimetry, particle size measurement or trajectography. Chapter 3 presents the new perspectives in 3-color holography applied to solid mechanics and fluid mechanics. Especially, a comparison between Michelson interferometer and interferometer using Wollaston prisms will be discussed. Chapter 4 is devoted to special techniques in holographic microscopy, with use of partial spatially coherent light sources; the use of a reduced coherence source is of interest for reducing the measurement noise; typical applications are detailed. Chapter 5 is devoted to applications of holographic microscopy in neurosciences. Chapter 6 presents digital holography in the infrared domain. Technology related to sensors and light sources are presented and digital holographic infrared interferometry is detailed and applied to high amplitude displacements of industrial aeronautic structures. Examples in NDT (non destructive testing) are also provided. Chapter 7 of the book, aims at presenting new techniques in the field of vibration measurement; especially, techniques based on high speed and ultimate sensitivity are described. Examples related to life sciences are discussed. Chapter 8 discusses about inverse problems in digital holography and demonstrates how a priori knowledge can be used to recover full information of the object scene even when recording is sparse.
This book provides comprehensive, state-of-the art coverage of photorefractive organic compounds, a class of material with the ability to change their index of refraction upon illumination. The change is both dynamic and reversible. Dynamic because no external processing is required for the index modulation to be revealed, and reversible because the index change can be modified or suppressed by altering the illumination pattern. These properties make photorefractive materials very attractive candidates for many applications such as image restoration, correlation, beam conjugation, non-destructive testing, data storage, imaging through scattering media, holographic imaging and display. The field of photorefractive organic material is also closely related to organic photovoltaic and light emitting diode (OLED), which makes new discoveries in one field applicable to others.
This book presents a substantial description of the principles and applications of digital holography. The first part of the book deals with mathematical basics and the linear filtering theory necessary to approach the topic. The next part describes the fundamentals of diffraction theory and exhaustively details the numerical computation of diffracted fields using FFT algorithms. A thorough presentation of the principles of holography and digital holography, including digital color holography, is proposed in the third part. A special section is devoted to the algorithms and methods for the numerical reconstruction of holograms. There is also a chapter devoted to digital holographic interferometry with applications in holographic microscopy, quantitative phase contrast imaging, multidimensional deformation investigations, surface shape measurements, fluid mechanics, refractive index investigations, synthetic aperture imaging and information encrypting. Keys so as to understand the differences between digital holography and speckle interferometry and examples of software for hologram reconstructions are also treated in brief. Contents 1.

This timely book presents cutting-edge developments by experts in the field on the rapidly developing and scientifically challenging area of full-field measurement techniques used in solid mechanics – including photoelasticity, grid methods, deflectometry, holography, speckle interferometry and digital image correlation. The evaluation of strains and the use of the measurements in subsequent parameter identification techniques to determine material properties are also presented. Since parametric identification techniques require a close coupling of theoretical models and experimental measurements, the book focuses on specific modeling approaches that include finite element model updating, the equilibrium gap method, constitutive equation gap method, virtual field method and reciprocity gap method. In the latter part of the book, the authors discuss two particular applications of selected methods that are of special interest to many investigators: the analysis of localized phenomenon and connections between microstructure and constitutive laws. The final chapter highlights infrared measurements and their use in the mechanics of materials. Written and edited by knowledgeable scientists, experts in their fields, this book will be a valuable resource for all students, faculties and scientists seeking to expand their understanding of an important, growing research area
The first monograph on this rapidly evolving area of research and development, this book presents both the theory and applications of new advances in 3D TV and display techniques. The theoretical concepts are illustrated by applied examples, numerical simulations and experimental results.

Das neue Buch des Pulitzer-Preisträgers Nach dem Hurrikan Katrina zieht ein Mann mit seinem Sohn durch das verwüstete Louisiana, um dessen Mutter zu finden. Jahre nach dem Fall der Mauer muss ein ehemaliger Aufseher sich im Stasi-Gefängnis Hohenschönhausen seiner Vergangenheit stellen. In Palo Alto findet eine schwerkranke Frau Trost im Gespräch mit einem Hologramm ihres verstorbenen Idols, Kurt Cobain – seine Worte »Mir bedeuten Dinge immer erst dann etwas, wenn sie nicht mehr da sind« fangen das Gefühl dieses Erzählungsbandes ein. Denn so unterschiedlich die Geschichten dieser Menschen auch sein mögen, steht doch über allen die Frage nach Erlösung – vom Chaos der Gegenwart, vom Schmerz, von den Geistern der Vergangenheit. Nach seinem Roman Das geraubte Leben des Waisen Jun Do, für den Adam Johnson mit dem Pulitzer-Preis ausgezeichnet wurde, begeistert er nun mit kraftvollen Geschichten – sie sind ebenso überraschend wie bewegend. »Der weiß, wie man eine gute Geschichte erzählt.« Zadie Smith

"[This book] is an excellent resource for the diverse practitioners and educators who are involved in this nascent area."--Cruse Bereavement Care "[This] book is innovative and timely, challengingthe reader to think 'out of the box.' Sofka,Cupit, and Gilbert provide a framework to explore thanatologyin an online universe while encouraging continuousresearch to adapt to this ever-changing digital world."--Death Studies "Historically we have always employed our foremost technology in the service of the dead. We have used whatever we had at our disposal to mourn, to support, to share memories and to tell stories. Carla J. Sofka, Illene Noppe Cupit, and Kathleen R. GilbertÖ reaffirm that principle reminding us that this new digital world both offers dramatic technologies and creates considerable opportunities to deal with dying, death, and grief. The editors are extraordinarily sensitive to the multiple ways that this new technology has impacted upon the death system or the ways that a society organizes behavior around dying and death. Dying, Death, and Grief in an Online Universe is bound to be a classic." Kenneth J Doka, PhD Professor, The College of New Rochelle Senior Consultant, The Hospice Foundation of America Modern communication technology has profoundly influenced societal practices and views about dying, death, and loss. This text, written for death educators, clinicians, researchers, and students of thanatology, provides current information about "thanatechnology," the communication technology used in providing death education, grief counseling, and thantology research. The book offers a broad overview of how the communication technology revolution affects individuals coping with end-of-life issues, death-related and non-death loss and grief, and implications of the "digital divide" between those who are knowledgeable about and have access to modern technology, and those who are not. It describes the proliferation of online support groups and social network sites to cope with loss, and mechanisms for the memorialization and commemoration of loss. It also highlights blogging as a mechanism for storytelling and SKYPE as a communication tool during times of loss and grief. The unique issue of disenfranchised grief experienced by online community members is also explored along with ethical issues. Appendices provide guidance regarding the online availability of different types of informational support, tools to evaluate the integrity of online resources, and ethical standards. Key Features: Examines the ways in which modern communication technology has revolutionized societal practices and views about dying, death, and loss Offers time-tested strategies for providing death education online Addresses ethical issues related to availability and use of technology Explores the implications of the "digital divide" between technology and non-technology users in relation to issues of death and loss Analyzes how technology has shaped and changed thanatology research
