"This book is a timely review of the various optical architectures, display technologies, and building blocks for modern consumer, enterprise, and defense head-mounted displays for various applications, including smart glasses, smart eyewear, and virtual-reality, augmented-reality, and mixed-reality headsets. Special attention is paid to the facets of the human perception system and the need for a human-centric optical design process that allows for the most comfortable headset that does not compromise the user's experience. Major challenges--from wearability and visual comfort to sensory and display immersion--must be overcome to meet market analyst expectations, and the book reviews the most appropriate optical technologies to address such challenges, as well as the latest product implementations"--
Miniaturization and mass replications have begun to lead the optical industry in the transition from traditional analog to novel digital optics. As digital optics enter the realm of mainstream technology through the worldwide sale of consumer electronic devices, this timely book aims to present the topic of digital optics in a unified way. Ranging from micro-optics to nanophotonics, and design to fabrication through to integration in final products, it reviews the various physical implementations of digital optics in either micro-refractives, waveguide (planar lightwave chips), diffractive and hybrid optics or sub-wavelength structures (resonant gratings, surface plasmons, photonic crystals ...
Diffractive optical elements (DOEs) are becoming more and more widely used in a braod range of fields, including telecommunications, optical computing, consumer electronics, laser material processing and the biomedical sciences, to manipulate light through micro-optical systems. In order to get the most out of such DOEs, knowledge of the design process, fabrication, packaging in a particular system, and operation is required. Digital Diffractive Optics discusses in detail the design and simulation of DOEs, before considering the main fabrication techniques. The increasingly important CAD/CAM tool requirements for the production of DOEs are covered, and a chapter is devoted to the crucial are...
Traditional macro-optics can be designed without complex design software tools. However, digital optics, especially wafer-scale micro-optics, require specific software and tools. There is often no analytical solution, and thus complex iterative optimization algorithms may be required. This book covers refractive and diffractive micro-optics, the iterative optimization process, and modeling and fabrication techniques crucial to this field. The ability to create hybrid systems capable of producing analog and digital functionality is also addressed.
An exploration of the neurological and behavioral mechanisms and processes involved in intrusive thinking. On any given day, unintended, recurrent thoughts intrude on our thinking and affect our behavior in ways that can be adaptive. Such thoughts, however, become intrusive and problematic when they are unwanted, become compulsive, or lead to socially or medically unacceptable behavior. This volume explores what goes on in our brains to create thought intrusions, and how these instrusions lead to maladaptive behavior.
This accessible introduction to multimodality illuminates the potential of multimodal research for understanding the ways in which people communicate. Readers will become familiar with the key concepts and methods in various domains while learning how to engage critically with the notion of multimodality. The book challenges widely held assumptions about language and presents the practical steps involved in setting up a multimodal study, including: formulating research questions collecting research materials assessing and developing methods of transcription considering the ethical dimensions of multimodal research. A self-study guide is also included, designed as an optional stand-alone reso...

"Long ago in 1945 all the nice people in England were poor, allowing for exceptions," begins The Girls of Slender Means, Dame Muriel Spark's tragic and rapier-witted portrait of a London ladies' hostel just emerging from the shadow of World War II. Like the May of Teck Club itself—"three times window shattered since 1940 but never directly hit"—its lady inhabitants do their best to act as if the world were back to normal: practicing elocution, and jostling over suitors and a single Schiaparelli gown. The novel's harrowing ending reveals that the girls' giddy literary and amorous peregrinations are hiding some tragically painful war wounds. Chosen by Anthony Burgess as one of the Best Modern Novels in the Sunday Times of London, The Girls of Slender Means is a taut and eerily perfect novel by an author The New York Times has called "one of this century's finest creators of comic-metaphysical entertainment."
