Tomographic density imaging using modified DF–DBIM approach

Multidimensional Tomographic Imaging Using Volume Holography

We propose the application of volume holography to fourdimensional (4-D) spatiospectral imaging. The proposed systems use materials and techniques developed for holographic data storage and interconnections to capture three-dimensional (3-D) spatial and one-dimensional (1-D) spectral information about a remote light source or scatterer. We analyze case studies of simple architectures using sphe...

A Tomographic Approach to Multi-pass Sar Imaging

In this communication we illustrate the employment of a tomographic technique to face the problem of synthetic aperture radar (SAR) imaging in a two-dimensional and scalar geometry and under a multi-frequency/multi-monostatic measurement configuration. In this context the different points of illumination and observation arise from different passes of the SAR sensor. We perform the analysis and ...

A Bayesian approach for nonlinear inverse scattering tomographic imaging

Quantitative Ultrasonic Tomographic Imaging

An ultrasonic transmission technique is described which images the velocity variation within metal parts. The arrival time of the first ultrasonic pulse to traverse the object is detected and displayed as a gray scale on a cathode ray tube while the part is being scannerJ hori:tontally and vertically. The velocity variation imaged within severa 1 cast turbine parts will be shown. ihe system can...

Tomographic imaging of foam.

The morphology of three-dimensional foams is of interest to physicists, engineers, and mathematicians. It is desired to image the 3-dimensional structure of the foam. Many different techniques have been used to image the foam, including magnetic resonance imaging, and short-focal length lenses. We use a camera and apply tomographic algorithms to accurately image a set of bubbles. We correct for...
