Outdoor Lighting Physics Vision And Perception

The present book is based on the experience of the author. The experience is mainly the result of years of research, of consulting work, and in participation in policy decision making in many felds, most, but not all, related to outdoor lighting. To some degree, the book represents the preference of the author. The selection of the subjects is based on more than 50 years of experience of what is desirable to know for persons engaged in scientifc research or practical application in the felds of lighting and vision. The subjects deal with a number of fundamental aspects. The theorists must have them at their fngertips, whereas the practical engineers may assume them as known in their daily work. The selection of subjects is based in part by the questions that came to the author over the years, but even more by the preference of the author himself. In this respect, it is a personal book. Thus, it should be stressed that the book is not a ‘handbook’ or even a ‘textbook’; many subjects that commonly are treated in such books are not included here. Not because they lack importance, but because the author feels that they are adequately treated elsewhere. Some relevant works are mentioned in the References. Over the years, the author has been engaged in giving courses on vision and lighting, lately more in particular on Masterclasses on a post-graduate or post-doctorate level.

Vision is about insight, and visual perception is about cognition - and they form the foundation of how we see the world. Duco A. Schreuder, a physicist and psychologist, explores the finer details of each in this groundbreaking book that explores human consciousness and perception. Sharing virtually everything he's learned over a varied career spanning more than sixty years, he examines a wide array of topics, including how we understand what we visually process, how we store and retrieve information, the role that neurons play in how what we see, and much more. While Schreuder isn't afraid to disagree with other leading thinkers, he relies on science and focuses on the facts behind it so you can understand lighting, visual perception, engineering design, and applied and experimental physics. Looking is about insight, whereas seeing is about knowledge, and you need to know how each one works to truly understand how humanity views the world. Whether you're an illuminating engineer considering the fundamentals of the trade or a student or professional in an allied discipline, you'll be well served by taking a closer look at Vision and Visual Perception.

Light: The Shape of Space Designing with Space and Light Lou Michel Every design professional who touches a space shapes the light and the feeling of that space. Architect, lighting engineer, interior designer, lighting or home furnishing manufacturer: each contributes an aesthetic layer, sometimes yielding unexpected results. All too often the best laid plans of one professional are unintentionally subverted by another. Removing surprises and guess work from design, Lou Michel, honored architectural lighting educator, has created Light: The Shape of Space, showing how to design with the effects of light rather than light itself. The book is a revolutionary resource for all design professionals and manufacturers of surfacing materials. Drawing on over fifteen years’ experience of research and teaching in the architectural Space and Light Laboratory at The University of Kansas, Michel masterfully examines the interrelationship of lighting and the design of architectural space as perceived not in architectural photos or paint chips and fabric swatches, but by human vision — the gateway to emotional response. The book was written for professionals who care about how people feel in the spaces they design, and focuses on the humanization of architecture. Taking a non-stylistic approach to design, Michel analyzes architecture from the perspective of how the users see their surroundings as they move through space. The reader will learn what pleases and what disturbs people based on how the human visual system responds to color, texture, pattern, and brightness. The book features principles of design for the student and professional, and is generously supported by illustrations and research. Michel also provides a method for evaluating the visual effectiveness of building materials and lighting systems, including those that will appear on the market long after this book is dog-eared. Michel unveils a groundbreaking luminance brightness rating system (LBR) and a nine-zone brightness scale to aid designers in previsualizing the appearance of surfacing materials at every stage of the design process, from schematics to development to refinement. Among the topics treated are: the interaction of lighting and spatial design color theory for space and light the luminance relationships between free-standing objects and the surrounding spatial boundaries against which they are seen the appearance of building materials in color and brightness when modified by light and spatial location lighting spatial connections, including the perception of rooms adjacent to the observer lighting and perception of spaces screened by architectural grilles creating lighted space Designing with the effects of light is both an art and a science. No other book on the market bridges that gap as successfully as Light: The Shape of Space.

The availability of electric lighting has changed the lives of people the world over, yet as a major user of electricity it has come under increasing scrutiny in recent years.

Promoting the design, application and evaluation of visually and electrically effective LED light sources and luminaires for general indoor lighting as well as outdoor and vehicle lighting, this book combines the knowledge of LED lighting technology with human perceptual aspects for lighting scientists and engineers. After an introduction to the human visual system and current radiometry, photometry and color science, the basics of LED chip and phosphor technology are described followed by specific issues of LED radiometry and the optical, thermal and electric modeling of LEDs. This is supplemented by the relevant practical issues of pulsed LEDs, remote phosphor LEDs and the aging of LED light sources. Relevant human visual aspects closely related to LED technology are described in detail for the photopic and the mesopic range of vision, including color rendering, binning, whiteness, Circadian issues, as well as flicker perception, brightness, visual performance, conspicuity and disability glare. The topic of LED luminaires is discussed in a separate chapter, including retrofit LED lamps, LED-based road and street luminaires and LED luminaires for museum and school lighting. Specific sections are devoted to the modularity of LED luminaires, their aging and the planning and evaluation methods of new LED installations. The whole is rounded off by a summary and a look towards future developments.

The Ashen Light of Venus -- a ghostly emission of light from the night side of our nearest planetary neighboris among the last unsolved mysteries of astronomical history. In the four centuries since the phenomenon was first reported, highly reputable visual observers of Venus have recorded seeing the Ashen Light, while others have spent a lifetime searching for it without once being convinced that they ever saw it. Is the Ashen Light a trick of the eye? The result of a defective lens? A real scientific event? Occasional references to the Ashen Light are scattered across the literature, yet no work to date has synthesized these records. This book therefore digs deep into the history of the mystery and our latest attempts to understand it, sifting through the clues that might explain whether it is caused by physics, is conjured up by the eye or brain, or a combination of both. This baffling story will appeal to amateur astronomers, hobbyists, and lay readers interested in joining the debate about one of the most elusive observable phenomena ever recorded in the night sky.

This chapter is focused on vision sensors based on both mammalian and insect vision systems. Typically, the former uses a single large-aperture lens system and a large, high-resolution focal plane array; the latter uses many small-aperture lenses, each coupled to a small group of photodetectors. The strengths and weaknesses of each type of design are discussed, along with some guidelines for designing such sensors. A brief review of basic optical engineering, including simple diffraction theory and mathematical tools such as Fourier optics, is followed by a demonstration of how to match an optical system to some collection of photodetectors. Modeling and simulations performed with tools such as Zemax and MATLAB® are described for better understanding of both optical and neural aspects of biological vision systems and how they may be adapted to an artificial vision sensor. A biomimetic vision system based on the common housefly, Musca domestica, is discussed.

Digital technology now enables unparalleled functionality and flexibility in the capture, processing, exchange, and output of color images. But harnessing its potential requires knowledge of color science, systems, processing algorithms, and device characteristics-topics drawn from a broad range of disciplines. One can acquire the requisite background with an armload of physics, chemistry, engineering, computer science, and mathematics books and journals- or one can find it here, in the Digital Color Imaging Handbook. Unprecedented in scope, this handbook presents, in a single concise and authoritative publication, the elements of these diverse areas relevant to digital color imaging. The first three chapters cover the basics of color vision, perception, and physics that underpin digital color imaging. The remainder of the text presents the technology of color imaging with chapters on color management, device color characterization, digital halftoning, image compression, color quantization, gamut mapping, computationally efficient transform algorithms, and color image processing for digital cameras. Each chapter is written by world-class experts and largely self-contained, but cross references between chapters reflect the topics' important interrelations. Supplemental materials are available for download from the CRC Web site, including electronic versions of some of the images presented in the book.
