Friedrich Kittler's lecture series provides a concise history of optical media from Renaissance linear perspective to late twentieth-century computer graphics. He begins by looking at European painting since the Renaissance in order to discern the principles according to which modern optical perception was organised. Kittler also discusses the development of various mechanical devices, like the camera obscura and the laterna magica, which were closely connected to the printing press and which played a pivotal role in the media war between the Reformation and the Counterreformation. After examining this history, Kittler then addresses the ways in which images were first stored and made to move through the development of photography and film. Kittler discusses the competitive relationship between photography and painting as well as between film and theater, as innovations like the Baroque proscenium or "picture-frame" stage evolved from elements that would later constitute cinema. The central question, however, is the impact of film on the ancient monopoly of writing, as it not only provoked new forms of competition for novelists but also fundamentally altered the status of books. In the final section, Kittler examines the development of electrical telecommunications and electronic image processing from television to computer simulations. In short, these lectures provide a comprehensive introduction to the history of image production, which is indispensable for anyone wishing to understand the prevailing audiovisual conditions of contemporary culture.

Light Propagation in Linear Optical Media describes light propagation in linear media by expanding on diffraction theories beyond what is available in classic optics books. In one volume, this book combines the treatment of light propagation through various media, interfaces, and apertures using scalar and vector diffraction theories. After covering the fundamentals of light and physical optics, the authors discuss light traveling within an anisotropic crystal and present mathematical models for light propagation across planar boundaries between different media. They describe the propagation of Gaussian beams and discuss various diffraction models for the propagation of light. They also explore methods for spatially confining (trapping) cold atoms within localized light-intensity patterns. This book can be used as a technical reference by professional scientists and engineers interested in light propagation and as a supplemental text for upper-level undergraduate or graduate courses in optics.

"This is very unique and promises to be an extremely useful guide to a host of workers in the field. They have given a generalized presentation likely to cover most if not all situations to be encountered in the laboratory, yet also highlight several specific examples that clearly illustrate the methods. They have provided an admirable contribution to the community. If someone makes their living by designing lasers, optical parametric oscillators or other devices employing nonlinear crystals, or designing experiments incorporating laser beam propagation through linear or nonlinear media, then this book will be a welcome addition to their bookshelf." —Richard Sutherland, Mount Vernon Nazarene University, Ohio, USA Laser Beam Propagation in Nonlinear Optical Media provides a collection of expressions, equations, formulas, and derivations used in calculating laser beam propagation through linear and nonlinear media which are useful for predicting experimental results. The authors address light propagation in anisotropic media, oscillation directions of the electric field and displacement vectors, the walk-off angles between the Poynting and propagation vectors, and effective values of the d coefficient for biaxial, uniaxial, and isotropic crystals. They delve into solutions of the coupled three wave mixing equations for various nonlinear optical processes, including quasi-phase matching and optical parametric oscillation, and discuss focusing effects and numerical techniques used for beam propagation analysis in nonlinear media, and phase retrieval technique. The book also includes examples of MATLAB and FORTRAN computer programs for numerical evaluations. An ideal resource for students taking graduate level courses in nonlinear optics, Laser Beam Propagation in Nonlinear Optical Media can also be used as a reference for practicing professionals.

Investigating the behavior of an atom in response to the applied electric field when the latter frequency is in resonance with the natural frequency of the atom is an interesting subject. Near resonance, some of the most interesting optical phenomena such as dispersion, and absorption are more pronounced. Moreover, considering resonant and near resonant interaction of light with two-level atoms, uncovers fascinating physical phenomena such as area theorem and self-induced transparency describing stable pulse propagation regimes in which the pulses maintain their identity. Existence of these optical structures in on-resonance optical media has not been investigated in detail. In this book, the on-resonance interaction of optical field with atoms is considered and the formation of several novel self-similar and kink waves in linear and nonlinear resonant media is discovered and theoretically explored. This book should be especially useful to professionals in Optics and Optoelectronics fields, or anyone else who may be considering utilizing near resonance optical structures such as similaritons, solitons, or optical kinks.

Abstract: Abstractofthesisentitled SolitonsandWavePropagation inHydrodynamicalandOpticalMedia submittedby Chun-ChungMAK forthedegreeofMasterofPhilosophy attheUniversityofHongKong inAugust2004 Solitons, which have been extensively studied over the past five decades, rep- resent one of the most important concepts in nonlinear science. These particle-like nonlinearwaveshavebeendemonstratedboththeoreticallyandexperimentally, and arebelievedtohavehighengineeringpotentialinsomeapplications. Theaimofthis studywastostudythesolitonswhichexistinsomeconfigurationsofhydrodynam- ical and optical media. In particular, soliton solutions of a number of completely integrablenonlinearevolutionequationsarenewlyobtainedorre-derived. The Hirota's bilinear method is adopted to obtain the exact soliton solutions in this study. This differentiation-based method, which requires no sophisticated mathematics, isabletoderiveexact, analyticsolutionsefficiently. An optical fiber system with decaying/amplifying and broadening/compressing effects is modelled by a variable coefficient nonlinear Schro]dinger (NLS) equa- tion. This equation is also able to describe the propagation of optical pulses in a dispersion-managed fiber system, averaged over one dispersion map. Bright anddark, one- and two-soliton solutions are obtained. These solitons are shown to havevaryingwavenumberandfrequencyintheirsolitonexpansions. Inadditionto the decaying and broadening effects, the bright solitons also demonstrate a special property, namely that the trajectory of their center of mass can have three possible modesinthex-t domain. A coupled NLS system with a group velocity mismatch is considered to be the relevant equation for a three-layer stratified shear flow. While the coupled NLS systemhasbeenstudiedindetail, theeffectofaddingagroupvelocitymismatchis still unknown. Dark one- and two-soliton solutions are obtained for an integrable system.
