Available in PDF, EPUB and Kindle. Book excerpt: In-line Fraunhofer holography has been developed and implemented at Los Alamos National Laboratory to measure particle distributions of fast moving particles. Holography is a unique diagnostic that gives unambiguous information on the size and shapes of particle distributions over a three dimensional volume. Currently, the capability of measuring particles two microns in size which travel many mm/[mu]sec has been demonstrated in hydrodynamic experiments at the Pegasus Pulsed Power Facility. Normally, for setting up an in- line holography experiment for measuring particles a few microns in size, the holographic film would be placed less than one centimeter from the particles. However, due to the high energy associated with the dynamic experiment, an optical relay system is used to relay the interference pattern 35 cm so that glass hologram will survive. After the hologram has been made the data must be extracted. This is accomplished by using a laser to reconstruct the data in space. This three dimensional image is then digitized via a CCD camera and a three axis actuator system. After the data has been digitized it is then analyzed with intelligent image processing algorithms. Details will be described below.
Book Synopsis Holography Manual by : P. G. Lingenfelder
Download or read book Holography Manual written by P. G. Lingenfelder and published by . This book was released on 1969 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holography first attracted widespread interest in this decade, with the application by Leith and Upatnieks of the laser as the source of coherent light. Literature on the subject trends to be general and theoretical. This document is a compilation of experimental techniques commonly used in the construction of holograms, including refinements developed at NELC. It supplies the needed practical approach to basic holography, and includes a description of the basic holographic laboratory and its equipment. (Author).
Book Synopsis The Techniques of Holographic Particle Sizing by : Robert L. Kurtz
Download or read book The Techniques of Holographic Particle Sizing written by Robert L. Kurtz and published by . This book was released on 1973 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Depending on the mechanism of particle production, the resultant particle size and velocity distribution may range over several orders of magnitude. In general, if particle size information is desired from a given type generator, one must resort to some form of experimental determination of the distribution. If the source of particle production is a dynamic one involving a reasonable volume, holography provides a tailor-made particle size and velocity distribution detector. This is evidenced by the fact that holography allows the entire volume to be recorded on one exposure without any interference with the volume of interest. Herein lies a very important characteristic of the holographic particle detection technique: It provides a holographic nondestructive testing technique in the fullest sense of the definition of nondestructive testing. This report provides a description of three different systems useful in this technique and includes the experimental results from one of the holographic systems which was used to detect particle size and velocity distribution from the Skylab waste tank.

Book Synopsis Particle Field Holography by : Chandra S. Vikram
Download or read book Particle Field Holography written by Chandra S. Vikram and published by Cambridge University Press. This book was released on 1992-07-23 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to provide a thorough and systematic description of the entire subject of particle field holography. The use of holography to study very small objects in a dynamic volume is a technique of importance for scientists and engineers across a variety of disciplines for obtaining information about the size, shape and velocity of small objects, such as dust particles, fuel droplets, raindrops, pollen, and bubbles. Professor Vikram has made major contributions to the field, and here provides a coherent, comprehensive and self-contained treatment of the theory, practice and applications. The volume is written to satisfy the needs of researchers in the technique, practicing engineers dealing with applications, and advanced students in science or engineering departments. All the necessary mathematical formulations, figures and photographs, experimental procedures and results, and literature citations are therefore included.
Book Synopsis An Analysis of the Techniques for Measuring Particle Size and Distribution from Fraunhofer Diffraction Patterns by : Ronald A. Belz
Download or read book An Analysis of the Techniques for Measuring Particle Size and Distribution from Fraunhofer Diffraction Patterns written by Ronald A. Belz and published by . This book was released on 1968 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The location and size of particles within a volume which is stationary or dynamic can be found by two techniques of coherent optics. In the first technique the volume is illuminated with coherent light and the resulting diffraction patterns are recorded in the far-field (Frauhofer region) of the particles. The particle information is found from the resultant density variations on the film. In the second technique the developed negative (a Fraunhofer hologram) is illuminated with coherent light and the particle field is reconstructed in three dimensions. This investigation is an analysis of these two techniques and their relative merits. Because magnification is important in the second technique the methods of magnifying the volume are discussed. It is found that reconstructing the volume from the hologram yields particle information which is easier to obtain than the information resulting from the diffraction patterns. The volume is also found to be easily and uniformly magnified by an imaging lens in the reconstruction process. (Author).

Book Synopsis Light Scattering by Particles in Water by : Miroslaw Jonasz
Download or read book Light Scattering by Particles in Water written by Miroslaw Jonasz and published by Elsevier. This book was released on 2011-08-29 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light scattering-based methods are used to characterize small particles suspended in water in a wide range of disciplines ranging from oceanography, through medicine, to industry. The scope and accuracy of these methods steadily increases with the progress in light scattering research. This book focuses on the theoretical and experimental foundations of the study and modeling of light scattering by particles in water and critically evaluates the key constraints of light scattering models. It begins with a brief review of the relevant theoretical fundamentals of the interaction of light with condensed matter, followed by an extended discussion of the basic optical properties of pure water and seawater and the physical principles that explain them. The book continues with a discussion of key optical features of the pure water/seawater and the most common components of natural waters. In order to clarify and put in focus some of the basic physical principles and most important features of the experimental data on light scattering by particles in water, the authors employ simple models. The book concludes with extensive critical reviews of the experimental constraints of light scattering models: results of measurements of light scattering and of the key properties of the particles: size distribution, refractive index (composition), structure, and shape. These reviews guide the reader through literature scattered among more than 210 scientific journals and periodicals which represent a wide range of disciplines. A special emphasis is put on the methods of measuring both light scattering and the relevant properties of the particles, because principles of these methods may affect interpretation and applicability of the results. The book includes extensive guides to literature on light scattering data and instrumentation design, as well as on the data for size distributions, refractive indices, and shapes typical of particles in natural waters. It also features a comprehensive index, numerous cross-references, and a reference list with over 1370 entries. An errata sheet for this work can be found at: http://www.tpdsci.com/Ref/Jonasz_M_2007_LightScatE.php *Extensive reference section provides handy compilations of knowledge on the designs of light scattering meters, sources of experimental data, and more *Worked exercises and examples throughout
