Handbook of Advanced Lighting Technology


Book Description

The Handbook of Advanced Lighting Technology is a major reference work on the subject of light source science and technology, with particular focus on solid-state light sources – LEDs and OLEDs – and the development of 'smart' or 'intelligent' lighting systems; and the integration of advanced light sources, sensors, and adaptive control architectures to provide tailored illumination which is 'fit to purpose.' The concept of smart lighting goes hand-in-hand with the development of solid-state light sources, which offer levels of control not previously available with conventional lighting systems. This has impact not only at the scale of the individual user, but also at an environmental and wider economic level. These advances have enabled and motivated significant research activity on the human factors of lighting, particularly related to the impact of lighting on healthcare and education, and the Handbook provides detailed reviews of work in these areas. The potential applications for smart lighting span the entire spectrum of technology, from domestic and commercial lighting, to breakthroughs in biotechnology, transportation, and light-based wireless communication. Whilst most current research globally is in the field of solid-state lighting, there is renewed interest in the development of conventional and non-conventional light sources for specific applications. This Handbook comprehensively reviews the basic physical principles and device technologies behind all light source types and includes discussion of the state-of-the-art. The book essentially breaks down into five major sections: Section 1: The physics, materials, and device technology of established, conventional, and emerging light sources, Section 2: The science and technology of solid-state (LED and OLED) light sources, Section 3: Driving, sensing and control, and the integration of these different technologies under the concept of smart lighting, Section 4: Human factors and applications, Section 5: Environmental and economic factors and implications

Limit of Vision


Book Description

A beautiful young scientist lies dead in a top-secret laboratory, the victim of an illegal experiment with the forbidden nanotechnology of intelligent organisms living at the limits of human vision. In Vietnam, a journalist probes a mysterious cult rumored to have awesome powers. As factions across the globe race to control this strange creation, a new stage in evolution is about to begin high above the Earth. (July)




Seeing


Book Description

One of the most remarkable things about seeing is how effortless this complex task appears to be. This book provides a comprehensive overview of research on the myriad complexities of this task. Coverage includes such classic topics as color, spatial, and binocular vision, areas that have seen a recent explosion of new information such as motion vision, image formation and sampling, and areas where new tools have allowed a better investigation into processes (e.g. neural representation of shape, visual attention).Seeing is a needed reference for researchers specializing in visual perception and is suitable for advance courses on vision.




Limits in Perception


Book Description

This book presents an analysis of limits in perception from the vantage point of the physicist, the engineer, the psychophysicist, the psychologist and the theorist. Limits in perception find their causal explanation at many logically and/or physically different levels. Some of the most fundamental bottlenecks are due to the quantum mechanical and atomistic structure of the microworld. Other simple constraints are due to the material constitution of sensory organs. For instance, the fact that the eye is predominantly composed of water limits both the optical quality and the available spectral window. The engineer uses knowledge on such limits to design equipment that optimizes human performance in daily life. Examples include room acoustics and visual displays. Psychophysicists and psychologists deal with limits on a quite different logical level. These limits constrain much of our perceptually guided behaviour. The book includes chapters on such topics as movement perception, binocular vision, illusory phenomena, language and perception, the perception of time. A few concluding chapters on fundamental limits imposed by information theoretical constraints on the coding and representation of sensed structure are included. Limits in Perception will be important reading material for scientists and/or engineers in the following fields: perception, experimental psychology, sensory biology, physics, neuroscience, human engineering, artificial intelligence, robotics, ophthalmology, audiology, psychonomics and ergonomics, remote sensing.




Foundations of Vision


Book Description

Designed for students, scientists and engineers interested in learning about the core ideas of vision science, this volume brings together the broad range of data and theory accumulated in this field.




Making Eye Health a Population Health Imperative


Book Description

The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.




Visual Perception


Book Description

This comprehensively updated and expanded revision of the successful second edition continues to provide detailed coverage of the ever-growing range of research topics in vision. In Part I, the treatment of visual physiology has been extensively revised with an updated account of retinal processing, a new section explaining the principles of spatial and temporal filtering which underlie discussions in later chapters, and an up-to-date account of the primate visual pathway. Part II contains four largely new chapters which cover recent psychophysical evidence and computational model of early vision: edge detection, perceptual grouping, depth perception, and motion perception. The models discussed are extensively integrated with physiological evidence. All other chapters in Parts II, III, and IV have also been thoroughly updated.




Visual Impairments


Book Description

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.
