Available in PDF, EPUB and Kindle. Book excerpt: Digital fringe projection (DFP) techniques are used for non-contact shape measurement of 3D images. In the rapidly expanding field of 3D high-speed imaging, the demand for DFP continues to grow due to the technology’s fast speed, flexibility, low cost, and high accuracy. High-Speed 3D Imaging with Digital Fringe Projection Techniques discusses the generation of digital fringe with digital video projection devices, covering a variety of core technical aspects. The book begins by establishing the theoretical foundations of fringe pattern analysis, reviewing various 3D imaging techniques while highlighting the advantages of DFP. The author then: Describes the differences between digital light processing (DLP), liquid crystal display (LCD), and liquid crystal on silicon (LCoS) Explains how to unwrap phase maps temporally and spatially Shows how to generate fringe patterns with video projectors Demonstrates how to convert phase to coordinates through system calibrations Provides a detailed example of a built-from-scratch 3D imaging system Incorporating valuable insights gained during the author’s 15+ years of 3D imaging research, High-Speed 3D Imaging with Digital Fringe Projection Techniques illuminates the pathway to advancement in high-speed 3D optical imaging using DFP.

Download or read book Recent Advances in Topography Research written by Jan Buytaert and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book at hand covers many of the different classes of topography/profilometry, and will give the reader an overview of different aspects of current profilometric methods. The intent is to show the possibilities, the state-of-the-art and some recent advances in the field by bringing together a non-exhaustive but diverse selection of profilometric methods. Some methods are fresh and unique like the one pixel profilometer or the sampling moiré method. Others are more consolidated, like Fourier transform profilometry but now in real-time, and even commercially available, like the newest time-of-flight cameras for 3D vision. The techniques in this book range from projection moiré to binary dithering pattern projection to areal surface mapping. They include an endoscopic implementation to an omnidirectional vision system and techniques using Fourier analysis to time-of-flight principles. Also, techniques applicable in biomedicine to engineering applications. Even from atomic force microscopy to optical coherence tomography, which both used as topographical means. Finally, some in-depth specialist reviews are included of new profilometric methods or new commercial profilometric devices. The book contains 12 chapters from selected authors from all over the world considered authorities in their field. The individual chapters are written to give a thorough introduction to each respective topographic method, and include a lot of background and abundant references, so that the book serves as a good introduction or reference.

Download or read book Plasmonics and Super Resolution Imaging written by Zhaowei Liu and published by CRC Press. This book was released on 2017-06-26 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasmonics is an emerging field mainly developed within the past two decades. Due to its unique capabilities to manipulate light at deep subwavelength scales, plasmonics has been commonly treated as the most important part of nanophotonics. Plasmonic-assisted optical microscopy techniques, especially super-resolution microscopy, have shown tremendous potential and attracted much attention. This book aims to collect cutting-edge studies in various optical imaging technologies with advanced performances that are enabled or enhanced by plasmonics. The basic working principles, development details, and potential future direction and perspectives are discussed. Edited by Zhaowei Liu, a prominent researcher in the field of super-resolution microscopy, this book will be an excellent reference for anyone in the field of nanophotonics, plasmonics, and optical microscopy.

Download or read book Fourier Ptychographic Imaging written by Guoan Zheng and published by Morgan & Claypool Publishers. This book was released on 2016-06-30 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book demonstrates the concept of Fourier ptychography, a new imaging technique that bypasses the resolution limit of the employed optics. In particular, it transforms the general challenge of high-throughput, high-resolution imaging from one that is coupled to the physical limitations of the optics to one that is solvable through computation. Demonstrated in a tutorial form and providing many MATLAB® simulation examples for the reader, it also discusses the experimental implementation and recent developments of Fourier ptychography. This book will be of interest to researchers and engineers learning simulation techniques for Fourier optics and the Fourier ptychography concept.

Download or read book Metasurface Holography written by Zi-Lan Deng and published by Springer Nature. This book was released on 2022-05-31 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The merging of metasurface and holography brings about unprecedented opportunities for versatile manipulation of light in terms of both far-field wavefront and near-field profile. In this book, a brief evolving history from surface plasmon polariton holography to metamaterial holography and finally to metasurface holography is introduced at first. Basic physical mechanisms that govern the phase modulation rules behind metasurface holography design are discussed later. Next, extended functionalities such as arbitrary polarization holography, vectorial holography, full-color holography, and hybrid holography achieved in the metasurface platform are presented. Surface wave and metagrating holography that bridges the on-chip surface wave and free-space wave is also introduced. In the end, we envisage practical applications of high-fidelity 3D holographic display, high-secure encryption, and high capacity digital encoding and also indicate remaining challenges based on metasurface holography.

Download or read book How to Shape Light with Spatial Light Modulators written by Carmelo Rosales-Guzmán and published by . This book was released on 2017 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structuring light is a ubiquitous laboratory tool, and computer-controlled devices such as spatial light modulators (SLMs) can reshape an input beam into almost any desired output beam. This Spotlight ranges the basic principles of these devices to some of the most advanced techniques in beam shaping. Many examples have been included to make this guide more comprehensive and help those shaping beams with a SLM for the first time. The provided examples are based in MATLAB, but they can be easily adapted to other programing languages. Readers need only an undergraduate level of mathematics and a basic knowledge of programming.

Download or read book Calibration and Orientation of Cameras in Computer Vision written by Armin Gruen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was conceived during the Workshop "Calibration and Orientation of Cameras in Computer Vision" at the XVIIth Congress of the ISPRS (In ternational Society of Photogrammetry and Remote Sensing), in July 1992 in Washington, D. C. The goal of this workshop was to bring photogrammetry and computer vision experts together in order to exchange ideas, concepts and approaches in camera calibration and orientation. These topics have been addressed in photogrammetry research for a long time, starting in the sec ond half of the 19th century. Over the years standard procedures have been developed and implemented, in particular for metric cameras, such that in the photogrammetric community such issues were considered as solved prob lems. With the increased use of non-metric cameras (in photogrammetry they are revealingly called "amateur" cameras), especially CCD cameras, and the exciting possibilities of acquiring long image sequences quite effortlessly and processing image data automatically, online and even in real-time, the need to take a new and fresh look at various calibration and orientation issues became obvious. Here most activities emerged through the computer vision commu nity, which was somewhat unaware as to what had already been achieved in photogrammetry. On the other hand, photogrammetrists seemed to ignore the new and interesting studies, in particular on the problems of orienta tion, that were being performed by computer vision experts.
