Book excerpt: 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.

Download or read book Light Propagation in Linear Optical Media written by Glen D. Gillen and published by CRC Press. This book was released on 2017-12-19 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Optical Data Storage written by Erwin R. Meinders and published by Springer Science & Business Media. This book was released on 2006-11-15 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an overview of recording principles, materials aspects, and applications of rewritable optical storage. Elements of data recording, including mark formation, eraseability, direct overwrite strategies, data quality and data stability are explained and extensively discussed. Throughout the book, a mark formation model is described and used to back-up measurement results and support the discussed applications. High-speed and dual-layer recording are analyzed in depth, with proposals to achieve higher performance.

Download or read book Ghostly Apparitions written by Stefan Andriopoulos and published by Princeton University Press. This book was released on 2013-06-09 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing together literature, media, and philosophy, Ghostly Apparitions provides a new model for media archaeology and its transformation of intellectual and literary history. Stefan Andriopoulos examines new media technologies and distinct cultural realms, tracing connections between Kant’s philosophy and the magic lantern’s phantasmagoria, the Gothic novel and print culture, and spiritualist research and the invention of television. As Kant was writing about the possibility of spiritual apparitions, the emerging medium of the phantasmagoria used hidden magic lanterns to startle audiences with ghostly projections. Andriopoulos juxtaposes the philosophical arguments of German idealism with contemporaneous occultism and ghost shows. In close readings of Kant, Hegel, and Schopenhauer, he traces the diverging modes in which these authors appropriated figures of optical media and spiritualist notions. The spectral apparitions from this period also intersect with the rise of popular print culture. Andriopoulos explores the circulation of ostensibly authentic ghost narratives and the Gothic novel, which was said to produce “reading addiction” and a loss of reality. Romantic representations of animal magnetism and clairvoyance similarly blurred the boundary between fiction and reality. The final chapter of Ghostly Apparitions extends this archaeology of new media into the early twentieth century. Tracing a reciprocal inter_action between occultism and engineering, Andriopoulos uncovers how theories and devices of psychical research enabled the emergence of television.

Download or read book Laser Beam Propagation in Nonlinear Optical Media written by Shekhar Guha and published by CRC Press. This book was released on 2017-12-19 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
