Contemporary Holography by C. S. Narayanamurthy Pdf

This book is unique in covering most of the developments on optical holographic techniques since holography’s invention in 1947 by Dennis Gabor. Starting from conventional holography with photopolymer recording techniques to CCD(Charge Coupled Device)-based digital holography, this book covers the spectrum of contemporary holographic techniques. The first chapter deals with conventional holographic methods using photographic plates in both in-line Gabor holography and off-axis holography. Then the second chapter covers principle and experimental techniques of the Conoscopic holography technique, and the third chapter deals with Computer generated holography. The fourth chapter discusses basic principles of dynamic holography using photorefractive crystals where the theory and experiments show how the photorefractive effect is used for dynamic recording of holograms. The fifth and sixth chapters extensively discuss the fundamentals of digital holography and unconventional coherence holography. In digital holography, two types of phase shifting methods which are dynamic and geometric phase shifting digital holographic techniques are elaborated with practical examples. Then, in the sixth chapter, the unconventional coherence holographic method describes a new holography using incoherent light sources. This book is intended for advanced undergraduate and first-year graduate-level students, as well as researchers looking for a complete resource in holography techniques.

Holography—A Critical Debate within Contemporary Visual Culture by Andrew Pepper Pdf

Artists have been exploring the spatial, conceptual and three-dimensional qualities of holography for over fifty years. Why, then, is there so little sustained critical pressure placed on this process, methodology and mode of visualisation which underpins the developing practice?In 1994, pioneering British artist Margaret Benyon, in her doctoral thesis, posed the question “How is Holography Art”, and offered a range of answers, by applying critical pressure to her considerable work in the field. Over 25 years later, we have used Benyon’s investigation as an invitation to ask more questions. This Special Issue in Arts brings together artists working with holography, as well as curators and long-term expert observers with an interest in the medium, to open up a more comprehensive discussion. They have reflected on the development of their work and its place within a cultural and critical framework. The curators and observers have employed a wider lens from their standpoints outside the field, but this is located firmly within current cultural discussions.There are more questions and certainly a need to increase the critical pressure around why holography could be one of the most significant ways of seeing and representing worlds and ideas today. We are surrounded by terrible art (painting, sculpture, print, photography, performance, digital, moving image), and holography has undoubtedly contributed to the visual flotsam clogging our vision. This publication aims to identify the importance of critical conversation, and the place holography holds within our current and complex media landscape.

Holography by Emilia Mihaylova Pdf

Holography - Basic Principles and Contemporary Applications is a collection of fifteen chapters, describing the basic principles of holography and some recent innovative developments in the field. The book is divided into three sections. The first, Understanding Holography, presents the principles of hologram recording illustrated with practical examples. A comprehensive review of diffraction in volume gratings and holograms is also presented. The second section, Contemporary Holographic Applications, is concerned with advanced applications of holography including sensors, holographic gratings, white-light viewable holographic stereograms. The third section of the book Digital Holography is devoted to digital hologram coding and digital holographic microscopy.

Holograms by Sean Johnston Pdf

This volume examines the history of the use of the hologram. Holograms are photographs of interference patterns that, when suitably illuminated, produce three-dimensional images. In its pure form, holography requires the use of laser light for illuminating the subject and for viewing the finished hologram. This work explores how holograms became embedded in modern popular culture. It traces their cultural roots in earlier visual technologies such as stereoscopes and 3-D movies, and examines how holograms of bewildering varieties added novel types of visual spectacle and appeal.

Holography by Freddy Monroy Pdf

This book depicts some differences from the typical scientific and technological literature on the theoretical study of holography and its applications. It offers topics that are not very commercial nor known, which will allow a different view of the field of optics. This is evident in chapters such as "Electron Holography of Magnetic Materials", "Polarization Holographic Gratings in Polymer Dispersed Formed Liquid Crystals", and "Digital Holography: Computer-generated Holograms and Diffractive Optics in Scalar Diffraction Domain". The readers will gain a different view of the application areas of holography and the wide range of possible directions that can guide research in the fields of optics.

Holographic Sensors by Ali Kemal Yetisen Pdf

This thesis presents a theoretical and experimental approach for the rapid fabrication, optimization and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. Developing non-invasive and reusable diagnostics sensors that can be easily manufactured will support the monitoring of high-risk individuals in any clinical or point-of-care setting. Sensor fabrication approaches outlined include silver-halide chemistry, laser ablation and photopolymerization. The sensors employ off-axis Bragg diffraction gratings of ordered silver nanoparticles and localized refractive index changes in poly (2-hydroxyethyl methacrylate) and polyacrylamide films. The sensors exhibited reversible Bragg peak shifts, and diffracted the spectrum of narrow-band light over the wavelength range λpeak ≈ 495-1100 nm. Clinical trials of glucose sensors in the urine samples of diabetic patients demonstrated that they offer superior performance compared to commercial high-throughput urinalysis devices. Lastly, a generic smartphone application to quantify colorimetric tests was developed and tested for both Android and iOS operating systems. The sensing platform and smartphone application may have implications for the development of low-cost, reusable and equipment-free point-of-care diagnostic devices.

Tales Side Up by John O'Loughlin Pdf

TALES SIDE UP is volume two of John O'Loughlin's Collected Short Prose and is comprised of three prior books dating from 1982-4. The title is a pun on tails, since the first volume was entitled 'Two Sides of the Same Coin' and that more or less metaphysical coin persists here with even greater ideological intensity, if on a basis excluding any heads-like commitment to an aphoristic appendix, as with Vol.1, and therefore concerned with a kind of fictional presentation of the ideological philosophy of Social Transcendentalism.
