Phase imaging using a polychromatic x-ray laboratory source.
We describe a quantitative phase imaging process using an x-ray laboratory-based source with an extremely broad bandwidth spectrum. The thickness of a homogeneous object can be retrieved by using separately spectrally weighted values for the attenuation coefficient and the decrement of the real part of the refractive index. This method is valid for a wide range of object types, including object...
متن کاملGhost Imaging with X Rays
C onventional imaging methods capture an image of an object by recording, in a multipixel detector, the intensity and color of a light beam that hits the object. The technique of ghost imaging is different. It forms an image of the object using correlations between the intensities of two light beams, an “object beam” that strikes the object and a “reference beam” that does not. Crucially, in th...
متن کاملSpeckle-based x-ray phase-contrast and dark-field imaging with a laboratory source.
We report on the observation and application of near-field speckles with a laboratory x-ray source. The detection of speckles is possible thanks to the enhanced brilliance properties of the used liquid-metal-jet source, and opens the way to a range of new applications in laboratory-based coherent x-ray imaging. Here, we use the speckle pattern for multimodal imaging of demonstrator objects. Mor...
متن کاملSpeckle-based x-ray phase-contrast imaging with a laboratory source and the scanning technique.
The speckle-based scanning method for x-ray phase-contrast imaging is implemented with a liquid-metal-jet source. Using the two-dimensional scanning technique, the phase shift introduced by the object is retrieved in both transverse orientations, and the limitations on spatial resolution inherent to the speckle-tracking technique are avoided. This method opens up possibilities of new high-resol...
متن کاملFactors Affecting In-line Phase Contrast Imaging with a Laboratory Microfocus X-ray Source
An in-line method of phase contrast imaging is investigated using a polychromatic laboratorybased microfocus X-ray source. The effect of source size is considered, and by introducing water into the imaging path the influence of water on the phase contrast is determined. The results confirm that good phase contrast images can be achieved using a polychromatic laboratory-based X-ray source, and d...
