View synthesis for kinetic depth X-ray imaging

open access: yes, 2012
This thesis reports the development and analysis of feature based synthesis of transmission X-ray images. The synthetic imagery is formed through matching and morphing or warping line-scan format images produced by a novel multi-view X-ray machine.

Phase contrast imaging with a laboratory-based microfocus X-ray source [PDF]

open access: yes, 2007
This project looks at the design of an in-line X-ray phase contrast imaging system, based around the Bede Microsource®, on a suitable scale for imaging small pathological samples. The system is applied to two test objects to assess feasibility of its use

Electron energy-loss spectroscopy: DFT modelling and application to experiment [PDF]

open access: yes, 2010
The all-electron density functional theory (DFT) code Wien2k has an established track record of modelling energy-loss near-edge structure (ELNES). The pseudopotential DFT code CASTEP can reproduce results found using Wien2k.

Dual-pulse laser induced breakdown spectroscopy in the vacuum ultraviolet with ambient gas: spectroscopic analysis and optimization of limit of detection of carbon and sulfur in steel [PDF]

open access: yes, 2012
Laser Induced Breakdown Spectroscopy (LIBS) in the vacuum ultraviolet (VUV) spectral region was applied to standard steel samples in dual-pulse excitation mode with an ambient gas. Two lasers were employed in collinear geometry, one as an ablation laser (

Automated materials discrimination using 3D dual-energy X-ray images [PDF]

open access: yes, 2002
The ability of a human observer to identify an explosive device concealed in complex arrangements of objects routinely encountered in the 2D x-ray screening of passenger baggage at airports is often problematic.
