Blue Light of the Screen is a memoir about the author's obsession with horror and the supernatural. Blue Light of the Screen is about what it means to be afraid -- about immersion, superstition, delusion, and the things that keep us up at night. A creative-critical memoir of the author's obsession with the horror genre, Blue Light of the Screen embeds its criticism of horror within a larger personal story of growing up in a devoutly Catholic family, overcoming suicidal depression, uncovering intergenerational trauma, and encountering real and imagined ghosts. As Cronin writes, she positions herself as a protagonist who is haunted by what she watches and reads, like an antiquarian in an M.R. James ghost story whose sense of reality unravels through her study of arcane texts and cursed archives. In this way, Blue Light of the Screen tells the story of the author's conversion from skepticism to faith in the supernatural. Part memoir, part ghost story, and part critical theory, Blue Light of the Screen is not just a book about horror, but a work of horror itself.
"In Glow Kids, Dr. Nicholas Kardaras will examine how technology-- more specifically, age-inappropriate screen tech, with all of its glowing ubiquity-- has profoundly affected the brains of an entire generation. Brain imaging research is showing that stimulating glowing screens are as dopaminergic (dopamine activating) to the brain's pleasure center as sex. And a growing mountain of clinical research correlates screen tech with disorders like ADHD, addiction, anxiety, depression, increased aggression, and even psychosis. Most shocking of all, recent brain imaging studies conclusively show that excessive screen exposure can neurologically damage a young person's developing brain in the same way that cocaine addiction can"--
Screens are ubiquitous today. They display information; present image worlds; are portable; connect to mobile networks; mesmerize. However, contemporary screen media also seek to eliminate the presence of the screen and the visibilities of its boundaries. As what is image becomes increasingly indistinguishable against the viewer's actual surroundings, this unsettling prompts re-examination about not only what is the screen, but also how the screen demarcates and what it stands for in relation to our understanding of our realities in, outside and against images. Through case studies drawn from three media technologies - Virtual Reality; holograms; and light projections - this book develops new theories of the surfaces on and spaces in which images are displayed today, interrogating critical lines between art and life; virtuality and actuality; truth and lies. What we have today is not just the contestation of the real against illusion or the unreal, but the disappearance itself of difference and a gluttony of the unreal which both connect up to current politics of distorted truth values and corrupted terms of information. The Post-Screen Through Virtual Reality, Holograms and Light Projections: Where Screen Boundaries Lie is thus about not only where the image's borders and demarcations are established, but also the screen boundary as the instrumentation of today's intense virtualizations that do not tell the truth. In all this, a new imagination for images emerges, with a new space for cultures of presence and absence, definitions of object and representation, and understandings of dis- and re-placement - the post-screen.
In the last decade, new displays have been developed at an ever-increasing pace: bulky cathode ray tubes have been replaced by flat panels and mobile phones, tablets, and navigation systems have proliferated. Seeing this explosion raises tantalizing questions about the future evolution of visual displays: Will printed displays be sold by the square yard and glued to the wall? Will disposable displays, powered by printed batteries and with built-in storage chips, talk to us from cereal boxes? Will we begin wearing display glasses that simulate any kind or number of virtual displays we would ever need? Will chip implants directly interface to our brains, eliminating the need for any displays at all? These and other questions are explored in Displays: Fundamentals & Applications, which describes existing and emerging display technology. The book begins by presenting the basics of wave optics, geometric optics, light modulation, visual perception, and display measures, along with the principles of holography. It then describes the technology and techniques behind projection displays, projector-camera systems, stereoscopic and autostereoscopic displays, computer-generated holography, and near-eye displays. In addition, the authors discuss how real-time computer graphics and computer vision enable the visualization of graphical 2D and 3D content. The text is complemented by more than 400 rich illustrations, which give readers a clear understanding of existing and emerging display technology.
Projection is a technology for generating large, high resolution images at a price point end users can afford. This allows it to be used in a wide variety of large-screen markets such as television and cinema. In addition, there are emerging small screen markets where a pocketable miniaturized projector can display images from mobile information devices such as smart phones or portable media players. Fully revised, this second edition of Projection Displays provides up-to-date coverage of the optical and mechanical systems in electronic projection displays. It takes into account major new developments in the many technologies needed to manufacture a projector display system. It presents a comprehensive review of projector architectures, systems, components and devices. Key new and updated features include: new material on light sources for projection displays; updated information on the human factors of projection displays including color gamuts, resolution and speckle; coverage of new image generating systems including LCOS and scanned laser systems; up to date information on front and rear projection screens; practical examples of projection display applications; models for predicting the performance of optical and mechanical systems This book is aimed at practicing engineers and researchers involved in the research, development, design and manufacture of projection displays. It includes key aspects from the many technologies contributing to projection systems such as illumination sources, optical design, electronics, semiconductor design, microdisplay systems and mechanical engineering. The book will also be of interest to graduate students taking courses in display technology and imaging science, as well as students of the many other engineering, physics and optics disciplines that lead into the field of projection displays. The Society for Information Display (SID) is an international society, which has the aim of encouraging the development of all aspects of the field of information display. Complementary to the aims of the society, the Wiley-SID series is intended to explain the latest developments in information display technology at a professional level. The broad scope of the series addresses all facets of information displays from technical aspects through systems and prototypes to standards and ergonomics
Over recent years there has been a vast expansion in the variety of imaging techniques available, and developments in machine specifications continue apace. If radiologists and radiographers are to obtain optimal image quality while minimising exposure times, a good understanding of the fundamentals of the radiological science underpinning diagnost
This book provides a concise overview of the field of radiology physics and its application in everyday practice. Beginning with an introduction to the fundamental concepts and the basics of radiation, the following sections review different techniques, from X-Ray production and ultrasound, to Doppler, mammography, computed tomography, and nuclear medicine procedures. Further topics include complex magnetic resonance concepts, radiation exposure monitoring, single-photon emission computed tomography, and positron emission tomography. Enhanced by radiological images and illustrations, each chapter explains the principles, function, application and limitations of the radiological technique in question. Key points Concise review of the field of radiology physics Covers complete range of radiology techniques, from basic to more complex Principles, function, application and limitations of each technique explained in detail Includes radiological images and illustrations to enhance learning
