Optical Holography: Materials, Theory and Applications provides researchers the fundamentals of holography through diffraction optics and an overview of the most relevant materials and applications, ranging from computer holograms to holographic data storage. Dr. Pierre Blanche leads a team of thought leaders in academia and industry in this practical reference for researchers and engineers in the field of holography. This book presents all the information readers need in order to understand how holographic techniques can be applied to a variety of applications, the benefits of those techniques, and the materials that enable these technologies. Researchers and engineers will gain comprehensive knowledge on how to select the best holographic techniques for their needs.

Have the countries' internal boundaries played a role in the response to the Covid-19 epidemic? What does the coronavirus crisis tell us about the sometimes strained relationship between national and regional/federal governments? This collective loock at the short- and medium term impact of the COVID-19 crisis on relations between central and regional governments.

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.

For residents living at national borders, the divisions between countries are rarely black and white, and often everyday interactions contribute to the creation of a cross-border region. This book examines this phenomenon in Cascadia, which runs along the Canada/US border in the Pacific Northwest. Placing people at the heart of the analysis, the book considers the everyday interactions and links which bind residents together and help to define Cascadia as a cross-border region. The book also assesses the impact that increased border security in the wake of 9/11 has had on border residents. Following a bottom-up approach rather than a top-down approach, the book examines how border security impacts the residents’ mobility, their representations of the border and, potentially the existence of a cross-border identity. Drawing on extensive original qualitative and quantitative data, this book will be of interest to researchers across border studies, geography, geopolitics, and cultural studies, as well as to policy makers and other stakeholders with an interest in cross-border cooperation.

Originally published in 1973, this volume presents some of the main approaches that were developed by French Africanists during the 1940s, 50s and 60s. The book covers social structure, kinship systems, economic change, ethnography, language, history and archaeology in West Africa.
