Basics of Virtual Reality


Book Description

Today, the reality we know can be recorded and reproduced true to reality using technical processes. Space and time are recreated virtually as a copy in artificial reality. However, the reproduction of virtual reality is not limited to a mere copy of what exists. A visitor to the virtual space does not have to be content with the pixelated image of the old familiar, but can encounter unreal phenomena in the illusory world that never existed in real life or are even physically impossible. This enables an expansion of the recorded reality and allows the perception of surprisingly new perspectives. A perspective denotes the perception of a fact from a certain point of view and corresponds to the way of looking at things. But a perspective is also the observation of a scene from a viewing position. From different perspectives the illusion of reality arises during the reproduction by observation. This vision is not based on imagination or hallucination, but is the basic function of virtual reality. This book describes the concepts, systems, and technologies used to create virtual reality from its ancient beginnings to the present, and provides a glimpse into a possible future. This book is a translation of the original German 1st edition Grundlagen der virtuellen Realität by Armin Grasnick, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

Terahertz Technology and Its Applications


Book Description

The Terahertz frequency range (0.1 – 10)THz has demonstrated to provide many opportunities in prominent research fields such as high-speed communications, biomedicine, sensing, and imaging. This spectral range, lying between electronics and photonics, has been historically known as “terahertz gap” because of the lack of experimental as well as fabrication technologies. However, many efforts are now being carried out worldwide in order improve technology working at this frequency range. This book represents a mechanism to highlight some of the work being done within this range of the electromagnetic spectrum. The topics covered include non-destructive testing, teraherz imaging and sensing, among others.




Image Sensors and Signal Processing for Digital Still Cameras


Book Description

Shrinking pixel sizes along with improvements in image sensors, optics, and electronics have elevated DSCs to levels of performance that match, and have the potential to surpass, that of silver-halide film cameras. Image Sensors and Signal Processing for Digital Still Cameras captures the current state of DSC image acquisition and signal processing technology and takes an all-inclusive look at the field, from the history of DSCs to future possibilities. The first chapter outlines the evolution of DSCs, their basic structure, and their major application classes. The next few chapters discuss high-quality optics that meet the requirements of better image sensors, the basic functions and performance parameters of image sensors, and detailed discussions of both CCD and CMOS image sensors. The book then discusses how color theory affects the uses of DSCs, presents basic image processing and camera control algorithms and examples of advanced image processing algorithms, explores the architecture and required performance of signal processing engines, and explains how to evaluate image quality for each component described. The book closes with a look at future technologies and the challenges that must be overcome to realize them. With contributions from many active DSC experts, Image Sensors and Image Processing for Digital Still Cameras offers unparalleled real-world coverage and opens wide the door for future innovation.




Computational Photography


Book Description

Computational Photography combines plentiful computing, digital sensors, modern optics, actuators, probes, and smart lights to escape the limitations of traditional film cameras and enables novel imaging applications. This book provides a practical guide to topics in image capture and manipulation methods for generating compelling pictures for graphics, special effects, scene comprehension, and art. The computational techniques discussed cover topics in exploiting new ideas in manipulating optics, illumination, and sensors at time of capture. In addition, the authors describe sophisticated reconstruction procedures from direct and indirect pixel measurements that go well beyond the traditional digital darkroom experience.










CMOS/CCD Sensors and Camera Systems


Book Description

The fully updated edition of this bestseller addresses CMOS/CCD differences, similarities, and applications, including architecture concepts and operation, such as full-frame, interline transfer, progressive scan, color filter arrays, rolling shutters, 3T, 4T, 5T, and 6T. The authors discuss novel designs, illustrate sampling theory and aliasing with numerous examples, and describe the advantages and limitations of small pixels. This monograph provides the very latest information for specifying cameras using radiometric or photometric concepts to consider the entire system--from scene to observer. Numerous new references have also been added.
