Book SynopsisThe authors of this book provide the first review of haptic optical tweezers, a new technique which brings together force feedback teleoperation and optical tweezers. This technique allows users to explore the microworld by sensing and exerting piconewton-scale forces with trapped microspheres. The design of optical tweezers for high-quality haptic feedback is challenging, given the requirements for very high sensitivity and dynamic stability. The concept, design process and specification of optical tweezers reviewed throughout this book focus on those intended for haptic teleoperation. The authors provide two new specific designs as well as the current state of the art. Furthermore, the remaining important issues are identified for further developments. Haptic optical tweezers will soon become an invaluable tool for force feedback micromanipulation of biological samples and nano- and micro-assembly parts.Table of ContentsPREFACE ix INTRODUCTION xi CHAPTER 1.

Book SynopsisRolf T. Borlinghaus erläutert die Ursachen für die klassische Begrenzung der Lichtmikroskopie und beleuchtet die neuen Super-Hochauflösungstechniken. Dies ist besonders aktuell, da der Nobelpreis 2014 für Chemie für die Entwicklung von Technologien vergeben wurde, die es nun ermöglichen, mit Lichtmikroskopen feinere Details aufzulösen, als es die klassische Theorie einschränkend vorhersagt. Diese neuen Methoden stellen aber nicht das bisherige Weltbild der Optik in Frage, vielmehr nutzen sie ganz andere Phänomene, um mittels klassischer Optik Positionsbestimmungen von Molekülen durchzuführen. Das ist theoretisch beliebig genau möglich.Trade Review“...

Martin Wooster, Environmental Monitoring and Modelling Research Group, King's College London'The third edition of this well known, highly respected and authoritative textbook contains a wealth of new material that captures advances in optical and microwave sensor systems and applications. University teachers will be delighted that the format remains the same; theory and technical detail are explained in clear language and supported by excellent diagrams and figures. The book incorporates good pedagogic principles … additional text boxes to help guide students not familiar with certain theoretical concepts, and review questions with problems to assist teachers to set extension exercises. [It] uses excellent examples, many of which are new in this edition, that clearly demonstrate why remote sensing data from a very wide range of sensors and platforms has such an impact on science and society today. Every student of remote sensing, whatever their level, and every library should have a copy of this excellent book.' Daniel Donoghue, Durham University'This is a comprehensive updating of a popular undergraduate and postgraduate text. The wealth of resources, new links and plates support the existing material superbly. The end references have been updated with new papers and sources and all the references are well integrated into the main text. … this is a superb text book and an excellent reference text. Dr W. G. Rees has done a superb job of updating what was already a well-loved and established text in a way which makes it a worthwhile investment for anyone studying the remote sensing and mapping of our planet.'

Book SynopsisPhotoalignment possesses significant advantages in comparison with the usual rubbing' treatment of the substrates of liquid crystal display (LCD) cells as it is a non-contact method with a high resolution. A new technique recently pioneered by the authors of this book, namely the photo-induced diffusion reorientation of azodyes, does not involve any photochemical or structural transformations of the molecules. This results in photoaligning films which are robust and possess good aligning properties making them particularly suitable for the new generation of liquid crystal devices. Photoalignment of Liquid Crystalline Materials covers state-of-the-art techniques and key applications, as well as the authors' own diffusion model for photoalignment. The book aims to stimulate new research and development in the field of liquid crystalline photoalignment and in so doing, enable the technology to be used in large scale LCD production.

Book SynopsisA groundbreaking guide dedicated exclusively to the MCRT method in radiation heat transfer and applied optics The Monte Carlo Ray-Trace Method in Radiation Heat Transfer and Applied Optics offers the most modern and up-to-date approach to radiation heat transfer modelling and performance evaluation of optical instruments. The Monte Carlo ray-trace (MCRT) method is based on the statistically predictable behavior of entities, called rays, which describe the paths followed by energy bundles as they are emitted, reflected, scattered, refracted, diffracted and ultimately absorbed. The author a noted expert on the subject covers a wide variety of topics including the mathematics and statistics of ray tracing, the physics of thermal radiation, basic principles of geometrical and physical optics, radiant heat exchange among surfaces and within participating media, and the statistical evaluation of uncertainty of results obtained using the method.

Book SynopsisThe scientific and technical basis underpinning modern measurement techniques used for electromagnetic quantities and phenonema is necessarily wide-ranging, as the electromagnetic environment spans all possible frequencies and wavelengths. Measurements must be applicable in fields as varied as nanotechnologies, telecommunications, meteorology, geo-location, radio-astronomy, health, biology, and many others. In order to adequately cover the many different facets of the topic, this book provides examples from the entire range of the electromagnetic spectrum — covering frequencies from several hertz to terahertz, and considering wavelength distances ranging from nanometers to light-years in optics. It then provides coverage of the various measurement techniques using electromagnetic waves for various applications, devoting chapters to each different field of application. This comprehensive book gives detailed information on: the various techniques and methods available to measure the key characteristics of electromagnetic waves, in terms of the local field and phase for a broad field of frequencies; determination of physical quantities such as distance, time, etc., using electromagnetic properties; new approaches to measurements in the field of electromagnetic distribution in complex structures media, such as biological tissues and in the nanosciences.

Book SynopsisDedicated to remote sensing images, from their acquisition to their use in various applications, this book covers the global lifecycle of images, including sensors and acquisition systems, applications such as movement monitoring or data assimilation, and image and data processing. It is organized in three main parts. The first part presents technological information about remote sensing (choice of satellite orbit and sensors) and elements of physics related to sensing (optics and microwave propagation). The second part presents image processing algorithms and their specificities for radar or optical, multi and hyper-spectral images. The final part is devoted to applications: change detection and analysis of time series, elevation measurement, displacement measurement and data assimilation. Offering a comprehensive survey of the domain of remote sensing imagery with a multi-disciplinary approach, this book is suitable for graduate students and engineers, with backgrounds either in computer science and applied math (signal and image processing) or geo-physics. About the Authors Florence Tupin is Professor at Telecom ParisTech, France. Her research interests include remote sensing imagery, image analysis and interpretation, three-dimensional reconstruction, and synthetic aperture radar, especially for urban remote sensing applications.

Book SynopsisThis book presents the basics of the non-invasive geophysical method for groundwater investigation, called Magnetic Resonance Sounding (MRS) or Surface Nuclear Magnetic Resonance (SNMR), and its practical application to the problems of groundwater localization and aquifer characterization. The method is based on the nuclear magnetic resonance (NMR) phenomenon and is selectively sensitive to groundwater. The main aims of the author are to teach the reader the basic principles of the method as well as to formulate consistent approximate models, leading to reasonably simple inverse problems. Containing an extensive bibliography, numerous practical and numerical examples as well as a detailed presentation of the nuts and bolts of the method based on the long-term experience of SNMR development and practical use, this book is useful for students, scientists and professional engineers working in the field of hydrogeophysics and hydrogeology.
