In continuation of the FRINGE Workshop Series this Proceeding contains all contributions presented at the 7. International Workshop on Advanced Optical Imaging and Metrology. The FRINGE Workshop Series is dedicated to the presentation, discussion and dissemination of recent results in Optical Imaging and Metrology. Topics of particular interest for the 7. Workshop are: - New methods and tools for the generation, acquisition, processing, and evaluation of data in Optical Imaging and Metrology (digital wavefront engineering, computational imaging, model-based reconstruction, compressed sensing, inverse problems solution) - Application-driven technologies in Optical Imaging and Metrology (high-resolution, adaptive, active, robust, reliable, flexible, in-line, real-time) - High-dynamic range solutions in Optical Imaging and Metrology (from macro to nano) - Hybrid technologies in Optical Imaging and Metrology (hybrid optics, sensor and data fusion, model-based solutions,multimodality) - New optical sensors, imaging and measurement systems (integrated, miniaturized, in-line, real-time, traceable, remote) Special emphasis is put on new strategies, taking into account the active combination of physical modeling, computer aided simulation and experimental data acquisition. In particular attention is directed towards new approaches for the extension of existing resolution limits that open the gates to wide-scale metrology, ranging from macro to nano, by considering dynamic changes and using advanced optical imaging and sensor systems.

The middle ear plays a vital role in the sense and sensitivity of hearing. Of the various characteristics that distinguish mammals from other vertebrates, several pertain specifically to the middle-ear system, such as the presence of three middle-ear bones and the four-layer composite structure of the tympanic membrane. The Middle Ear attempts to elucidate the role this system plays in sound transmission, as viewed from both scientific and clinical perspectives.

Interferometry makes use of the principle of superposition to combine separate waves together in a way that will cause the result of their combination to have some meaningful property that is diagnostic of the original state of the waves. This new book presents current research in the principles and applications of interferometry. Topics discussed include speckle methods for material analysis; using White Light Interferometry for accurate topographic measurements of surfaces; cyclic path interferometric configuration applications; phase-stepping algorithms; periodic error measurement for heterodyne interferometry and high contrast Schlieren diffraction interferometry.

An interferometer is a device that splits a beam of light into two beams. In this book, the most prominent active interferometers are discussed from a research point of view focusing on three variants. Among the many topics of research included in this book are: results of adaptive interferometers operation based on photorefractive crystals and the effect of the non-steady state photo-electromotive force, a reanalysis of the framework of the'magnetic'components of gravitational waves, the development of a real-time in situ surface height measuring system based on phase shifting interferometer, a review of a single-channel interferometer for generating digital Fresnel holograms of 3-D real-existing objects illuminated by incoherent light, a study on the volumetric changes which occur during photopolymerization under nonisothermal conditions and a discussion of the electrochemical Koesters interferometer technique used for the determination of changes of surface stress of solid electrodes. In order to cope with the unceasing bandwidth demand fueled by the massive use of the Internet, this book includes a review of the two main types of switching devices, namely the SOA-assisted Sagnac switch(TOAD) and the Ultrafast Nonlinear Interferometer. Application of Laser interferometry technique for investigation of acoustic wave fields is considered as well.

21 years ago it was a joint idea with Hans Rottenkolber to organize a workshop dedicated to the discussion of the latest results in the automatic processing of fringe patterns. This idea was promoted by the insight that automatic and high precision phase measurement techniques will play a key role in all future industrial and scientific applications of optical metrology. A couple of months later more than 50 specialists from East and West met in East Berlin, the capital of the former GDR, to spend 3 days with the discussion of new principles of fringe processing. In the stimulating atmoshere the idea was born to repeat the workshop and to organize the meeting in an olympic schedule. And thus meanwhile 20 years have been passed and we have today Fringe number six. However, such a workshop takes place in a dynamic environment. Therefore the main topics of the previous events were always adapted to the most interesting subjects of the new period. In 1993 the workshop took place in Bremen and was dedicated to new principles of optical shape measurement, setup calibration, phase unwrapping and nondestructive testing, while in 1997 new approaches in multi-sensor metrology, active measurement strategies and hybrid processing technologies played a central role. 2001, the first meeting in the 21st century, was focused to optical methods for micromeasurements, hybrid measurement technologies and new sensor solutions for industrial inspection.

Professor Ars has gathered together an excellent group of otologists who start with the initial causes of the problems and move on to look for the essentials of success. Having identified these, they go on to explore how we can lay the foundations to achieve them. Finally, they look at the operative procedures they consider most likely to achieve success. This is an excellent book, which should improve the thinking behind surgery for CSOM. Alan G. Kerr, OBE, FRCS.

In the summer of 2006, the 5th International Symposium on Middle Ear Mechanics in Research and Otology was held at the University of Zurich, Switzerland. More than 250 participants from 33 countries in all five continents came together to present their most current research results, exchange their knowledge in practical applications, to discuss open questions and discover new unsolved problems.This book includes representative, peer-reviewed articles of the lectures and papers presented during the symposium, and thereby gives an overview of the ongoing research and current knowledge in the function and mechanics of the normal, diseased and reconstructed middle ear. It covers basic research, engineering and clinical aspects of evaluation, diagnosis and surgery of the middle ear as well as implantable hearing devices in a very broad and interdisciplinary way. Following the tradition of the organizers of the previous conferences to collect the contributions of the symposium, this volume further initialized and promotes many fruitful discussions on middle ear mechanics with different points of view.

Acute and chronic ear disease continues to be one of the leading diseases of childhood. Understanding eustachian tube function and management remains one of the most important aspects in controlling inflammatory ear disease. Chronic ear disease requires elaborate surgical interventions designed to bypass eustachian tube dysfunction and/or poor mastoid aeration, since surgical management of the eustachian tube has been elusive. Our understanding of the ear and hearing continues to expand at record pace, as auditory neuroscientists discover the fundamental molecular structure and function of the.
