      Continuing in the steps of its predecessors, the fourth edition of Practical Holography provides the most comprehensive and up-to-date resource available. Focused on practical techniques in holography at all levels, it avoids any unnecessary mathematical theory. Features of the Fourth Edition Highlights new information on color holograms, sensitive materials, and state-of-the-art processing. Digital holography and digital image processing are twins born by computer era. They share origin, theoretical base, methods and algorithms. The present book describes these common fundamentals principles, methods and algorithms including image and hologram digitization, data compression, digital transforms and efficient computational algorithms, statistical and Monte-Carlo methods, image Reviews: 5.

    retains the digital holographic information such as fringe pattern can be easily displayed in a holographic display system. If the decoded data is a 3D model or a depth-and-texture im‐ age, the adequate 3D information to the corresponding display system must be extracted. 2. Characteristics of digital holograms. The measurement speed is determined by the frame rate of the image sensor, the data transfer speed, and the calculation time for the image-reconstruction procedure. A modern high-speed camera has a frame rate of 1 Mfps, and such a camera has been used to perform digital holographic recording with a frame rate of 10 6 fps. In contrast, the high.

      Recently, we developed a micro digital holographic particle tracking velocimetry (micro-DHPTV) method for high time-resolution flow field measurement in a micro-channel. The system consists of an objective lens, a high-speed camera and a single high-frequency double-pulsed laser. The volume of the system is µm × µm × 40 µm. The.   G. Nanda, A. Cable, and V. M.

A high-resolution charge coupled device (CCD) camera ( x ) supported by an image digitized board (OCULUS), with software in C language is used to read the photo- graphic contoured image or directly the holographic image.

The system consists of a coherent-optical configuration to generate the Fourier irradiance of the radiographic image and a digital computer to process the data. The interface is a TV camera. The technique was tested in a pilot study using sixty-four chest films of normal and abnormal lungs.

Topics include a brief introduction to the history, types, and materials of holography; the basic principles of analog and digital holography; a detailed explanation of famous fringe-deciphering techniques for holographic interferometry; holographic and non-holographic 3D display technologies; and cutting-edge concepts such as compressive.

Holographic Data Storage Digital data storage using volume holograms offers high density and fast readout. Current research concentrates on system design, understanding and combating noise, and developing appropriate storage materials. Possible applications include fast data servers and high-capacity optical disks.

Although hologram interferometry has had numerous and widespread applications, it has faced two persistent impediments that derive from the photographic nature of holography itself.

Traditionally holograms have been recorded in photographic materials which require chemical or thermoelectric processing before they can be used to generate an image. This constitutes the first impediment: a. Fourier optics and digital holography.

The book is also useful for scientists and engineers, and for those who simply want to learn about optical image processing and digital holography.

We believe in the inclusion of MATLAB® in the textbook because digital holography relies heavily on digital computations to process holographic data. digital holographic data: an overview, in SPIE Proc.

Dufaux, Digital Holographic Data Representation and Compression, Academic Press (to be published). Digital image processing techniques are needed in order to recover the object information encoded in fringe patterns generated in a determined interferometric setup.

Main fringe analysis techniques are reviewed in order to give the reader the most fundamental insights for the interpretation of interferograms. Phase shifted, open fringe, lateral shear and other types of interferograms make use. This book begins with a brief introduction of the history of holography, types of holograms, and materials used for hologram recording, followed by a discussion of the basic principles of analog and digital holography and an indepth explanation of some of the most famous fringe-deciphering techniques for holographic interferometry.

Lee et al. were able to fit all six parameters directly to data obtained from an inline digital holographic microscope using a least-squares approach. They used the method to both locate and characterize wavelength-sized, spherical colloidal particles, obtaining the axial position to a precision of 10 nm using nm light.In continuation of the FRINGE Workshop Series this Proceeding contains all contributions presented at the 7.
