A Particle Imaging and Analysis System for Underwater Holograms
نویسنده
چکیده
Pulsed holography is an important technique for the study of particle fields: it allows instantaneous, non-invasive high-resolution recording, and the later replay of real images from which one can obtain the size, shape, position, and – if multiple exposures are made – velocity of every object in the sample volume. This Chapter will discuss various issues encountered during the design of a hologram replay machine, with particular emphasis on the physical design of the instrument, and on the volume scanning and image processing techniques needed to pick out the useful information from the terabyte amounts of raw data produced on each hologram.

Optimum Design of a Five-Phase Permanent Magnet Synchronous Motor for Underwater Vehicles by use of Particle Swarm Optimization
Permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. One of the interesting applications of such motors is in underwater vehicles. In these cases, reaching to minimum volume and high torque of the motor are the major concern. Design optimization can enhance their merits considerably, thus reduce volum...

Digital holograms, when combined with tracer particles, can be used for examining otherwise-invisible fluid flows. These holograms can be captured with standard digital imaging equipment, however processing them to extract tracer or particle locations is computationally expensive. Exacerbating the issue is that hundreds or thousands of holograms must be reconstructed to analyze a single flow. P...
متن کاملMicroparticle characterization using digital holography
Digital holography is an effective 3D imaging technique, with the potential to be used for particle size measurements. A digital hologram can provide reconstructions of volume samples focused at different depths, overcoming the focusing problems encountered by other imaging based techniques. Several particle analysis methods discussed in the literature consider spherical particles only. With th...
متن کاملUnderwater digital holography for studies of marine plankton.
Conventional and digital holographies are proving to be increasingly important for studies of marine zooplankton and other underwater biological applications. This paper reports on the use of a subsea digital holographic camera (eHoloCam) for the analysis and identification of marine organisms and other subsea particles. Unlike recording on a photographic film, a digital hologram (e-hologram) i...
