Book Description
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.

Book Description
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.

Book Description
"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.

Book Description
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.

Book Description
This book addresses the persistence of the optical media piracy trade in the Philippines and Vietnam. It goes beyond arguments of defective law enforcement and copyright legal systems by applying sociological perspectives to examine the socio-economic forces behind the advent of piracy in the region. Using documentary and ethnographic data, in addition to resistance and ecological theories in sociology of law and technology as the overall theoretical framework, the book investigates factors that contribute to this phenomenon and factors that impede the full formalization of the optical media trade in the two countries. These factors include the government’s attitude towards the informal sector and strong resistance to tougher IPR protection, unstable and sometimes conflicting policies on technologies, burdensome business registration process and weak enforcement of business regulations, bureaucratic corruption and loopholes in law enforcement system as well as trade ties with China. In addition to that, the book highlights the social background of the actors behind the illegal business of counterfeit CDs and DVDs, thereby explaining the reasons they continue to persist in this type of trade. It invites policymakers, law enforcers, advocates of anti-piracy groups, and the general public to use a more holistic lens in understanding the persistence of copyright piracy in developing countries, shifting the blame from the moral defect of the traders to the current problematic copyright policy and enforcement structure, and the difficulty of crafting effective anti-piracy measures in a constantly evolving and advancing technological environment.

Book Description
The kaleidoscope, the stereoscope, and other nineteenth-century optical toys analyzed as “new media” of their era, provoking anxieties similar to our own about children and screens. In the nineteenth century, the kaleidoscope, the thaumatrope, the zoetrope, the stereoscope, and other optical toys were standard accessories of a middle-class childhood, used both at home and at school. In Playful Visions, Meredith Bak argues that the optical toys of the nineteenth century were the “new media” of their era, teaching children to be discerning consumers of media—and also provoking anxieties similar to contemporary worries about children's screen time. Bak shows that optical toys—which produced visual effects ranging from a moving image to the illusion of depth—established and reinforced a new understanding of vision as an interpretive process. At the same time, the expansion of the middle class as well as education and labor reforms contributed to a new notion of childhood as a time of innocence and play. Modern media culture and the emergence of modern Western childhood are thus deeply interconnected. Drawing on extensive archival research, Bak discusses, among other things, the circulation of optical toys, and the wide visibility gained by their appearance as printed templates and textual descriptions in periodicals; expanding conceptions of literacy, which came to include visual acuity; and how optical play allowed children to exercise a sense of visual mastery. She examines optical toys alongside related visual technologies including chromolithography—which inspired both chromatic delight and chromophobia. Finally, considering the contemporary use of optical toys in advertising, education, and art, Bak analyzes the endurance of nineteenth-century visual paradigms.
