The present book is based on the experience of the author. The experience is mainly the result of years of research, of consulting work, and in participation in policy decision making in many felds, most, but not all, related to outdoor lighting. To some degree, the book represents the preference of the author. The selection of the subjects is based on more than 50 years of experience of what is desirable to know for persons engaged in scientifc research or practical application in the felds of lighting and vision. The subjects deal with a number of fundamental aspects. The theorists must have them at their fngertips, whereas the practical engineers may assume them as known in their daily work. The selection of subjects is based in part by the questions that came to the author over the years, but even more by the preference of the author himself. In this respect, it is a personal book. Thus, it should be stressed that the book is not a 'handbook' or even a 'textbook'; many subjects that commonly are treated in such books are not included here. Not because they lack importance, but because the author feels that they are adequately treated elsewhere. Some relevant works are mentioned in the References. Over the years, the author has been engaged in giving courses on vision and lighting, lately more in particular on Masterclasses on a post-graduate or post-doctorate level.

This title includes a number of Open Access chapters. Spectroscopy is a powerful technique that utilizes the interaction of light with matter. Analysis of various spectra can yield important physical characteristics of matter, including chemical composition, temperature, luminosity, mass, and more. The uses and implications of spectroscopy are very broad, with practical uses in many fields of science, including astronomy, medicine, analytic chemistry, material science, geology, and more. Researchers are constantly discovering new applications of spectroscopy, and it is expected to play an ever-increasing role in nanotechnology and superconductivity. This book brings together a diverse collection of new research advances in spectroscopy.

This book analyzes novel possibilities offered to the telecommunication engineer in designing tomorrow's optical networks. Currently, optical and optoelectronic technologies make possible the realization of high-performance optical fiber communication systems and networks with the adoption of WDM configurations and both linear and nonlinear optical amplifications. The last step for increasing network throughput is represented by the implementation of multidimensional modulation formats in coherent optical communication systems, which enable increasing the bit rate/channel toward 400 Gbit/s/channel and beyond. Following this approach, the main emphasis is placed on innovative optical modulations. Multidimensional Modulations in Optical Communication Systems is an essential guide to the world of innovative optical communications from the point of view of growing capacity and security. It guides researchers and industries with the aim to exploring future applications for optical communications.

Since the first edition of this book was published several new developments have been made in the field of the moire theory. The most important of these concern new results that have recently been obtained on moire effects between correlated aperiodic (or random) structures, a subject that was completely absent in the first edition, and which appears now for the first time in a second, separate volume. This also explains the change in the title of the present volume, which now includes the subtitle "Volume I: Periodic Layers". This subtitle has been added to clearly distinguish the present volume from its new companion, which is subtitled "Volume II: Aperiodic Layers". It should be noted, however, that the new subtitle of the present volume may be somewhat misleading, since this book also treats (in Chapters 10 and 11) moire effects between repetitive layers, which are, in fact, geometric transformations of periodic layers, that are generally no longer periodic in themselves. The most suitable subtitle for the present volume would therefore have been "Periodic or Repetitive Layers", but in the end we have decided on the shorter version.

the model for low-PMD ?bers; Nicolas Gisin covered the increasingly important topic of the interaction of PMD with polarization dependent loss. Other topics that were included in the school were: "PMD models," which was covered byAntonio Mecozzi and Mark Shtaif; "Interaction of PMD with nonlinearity and chromatic dispersion," which was covered by Curtis Menyuk; "PMD measurement techniques," which was covered by Paul Williams and by Marco Schiano in two separate lectures; "Spatially resolved measurement of ?ber polarization properties," which was covered by Luca PalmieriandAndreaGaltarossa;"PMDimpactonopticalsystems,"whichwascovered by Magnus Karlsson and by Francesco Matera in two separate lectures; "Polarization effects in recirculating loops," which was covered by Brian Marks, Gary Carter, and Yu Sun; "PMD Emulation," which was covered byAlan Willner and Michelle Hauer; and, ?nally, "Applications of importance sampling to PMD," which was covered by Gino Biondini, Bill Kath, and Sarah Fogal. Dipak Chowdhury worked withArtis and VPI-two producers at that time of commercial software for modeling optical ?ber communications systems-to present a lecture that covered numerical modeling of PMD. Additionally, we had lectures on special topics by Hermann Haus, Jim Gordon, Herwig Kogelnik, and Carlo Someda. Finally, we had a poster session, which gave the lecturers the opportunity to learn something from our participants. The feedback that we received from the participants and the lecturers was ov- whelmingly positive. This success was due to the great time and energy that all the instructors put into their lectures.

This self-contained monograph provides a mathematically simple and physically meaningful model which unifies gravity, electromagnetism, optics and even some quantum behavior. The simplicity of the model is achieved by working in the frame of an inertial observer and by using a physically meaningful least action principle. The authors introduce an extension of the Principle of Inertia. This gives rise to a simple, physically meaningful action function. Visualizations of the geometryare obtained by plotting the action function. These visualizations may be used to compare the geometries of different types of fields. Moreover, a new understanding of the energy-momentum of a field emerges. The relativistic dynamics derived here properly describes motion of massive and massless objects under the influence of a gravitational and/or an electromagnetic field, and under the influence of isotropic media. The reader will learn how to compute the precession of Mercury, the deflection of light, and the Shapiro time delay. Also covered is the relativistic motion of binary stars, including the generation of gravitational waves, a derivation of Snell's Law and a relativistic description of spin. We derive a complex-valued prepotential of an electromagnetic field. The prepotential is similar to the wave function in quantum mechanics. The mathematics is accessible to students after standard courses in multivariable calculus and linear algebra. For those unfamiliar with tensors and the calculus of variations, these topics are developed rigorously in the opening chapters. The unifying model presented here should prove useful to upper undergraduate and graduate students, as well as to seasoned researchers.

With clear illustrations throughout and without recourse to quantum mechanics, the reader is invited to revisit unsolved problems lying at the foundations of theoretical physics. Maxwell and his contemporaries abandoned their search for a geometrical representation of the electric and magnetic fields. The wave-particle dilemma and Bose-Einstein statistical counting have resulted in unsatisfactory non-realistic interpretations. Furthermore, a simple structure of the hydrogen atom that includes hyperfine levels is still wanting. Working with the latest experimental data in photoionics a proposed solution to the wave-particle dilemma is suggested based on an array of circular-polarized rays. The Bose-Einstein counting procedure is recast in terms of distinguishable elements. Finally, a vortex model of a 'particle' is developed based on a trapped photon. This consists of a single ray revolving around a toroidal surface, and allows a geometrical definition of mass, electric potential, and magnetic momentum. With the adjustment of two parameters, values to 4 dp for the hyperfine frequencies (MHz) of hydrogen can be obtained for which a computer program is available.

This book presents a direct measurement of quantum back action, or radiation pressure noise, on a macroscopic object at room temperature across a broad bandwidth in the audio range. This noise source was predicted to be a limitation for gravitational wave interferometers in the 1980s, but it has evaded direct characterization in the gravitational wave community due to the inherent difficult of reducing thermal fluctuations below the quantum back action level. This back action noise is a potential limitation in Advanced LIGO and Advanced Virgo, and Cripe's experiment has provided a platform for the demonstration of quantum measurement techniques that will allow quantum radiation pressure noise to be reduced in these detectors. The experimental techniques Cripe developed for this purpose are also applicable to any continuous measurement operating near the quantum limit, and could lead to the possibility of observing non-classical behavior of macroscopic objects.
