Novel concepts in phase shifting interferometry and their applications to holographic moiré

Abhijit Patil

To date, no phase shifting technique has been implemented that accommodates the requirements inherent in holographic moiré . In the present form of measurement, only the value of one component of difference in displacement carried on moiré is quantified, w ...

Phase contrast X-ray imaging

Giorgio Margaritondo

In the last decade X-ray imaging based on phase contrast greatly advanced thanks to the use of unmonochromatic synchrotron hard X-rays. The recent advances are going beyond microradiology and microtomography to reach nanometre scale. This paper reviews bas ...

Real-time radiology in the microscale

Giorgio Margaritondo

We present several examples of the applications of a novel microradiology approach based on phase contrast enhancement using unmonochromatized synchrotron X-rays. The approach-mostly implemented and realized at the International Consortium on Phase Contras ...

Real-time radiology in the microscale

Giorgio Margaritondo

We present several examples of the applications of a novel microradiology approach based on unmonochromatized synchrotron x-rays. The approach - mostly implemented on the ICPCIR (International Consortium on Phase Contrast Imaging and Radiology) Beamline at ...

Synchrotron microangiography with no contrast agent

Giorgio Margaritondo, Amela Groso

Coherent x-rays from synchrotron sources are increasingly used in non-conventional radiological techniques ('phase-contrast' radiology). Our experiments demonstrate that by using white (unmonochromatic) radiation and a time-resolving system, it is possible ...

Coherent x-ray scattering

This is a tutorial paper on the properties of partially coherent hard x-ray beams and their use in the structural analysis of condensed matter. The role of synchrotron radiation in the generation of coherent x-ray beams is highlighted and the requirements ...

International consortium on phase contrast imaging and radiology beamline at the Pohang Light Source

Giorgio Margaritondo

We describe the general characteristics and the first result of a new synchrotron beamline at the Pohang Light Source in Korea. The beamline, operated by a Korean-Taiwanese-Swiss consortium, is dedicated to microimaging experiment in real time with coheren ...

Edge-enhanced radiology with broadband synchrotron X-rays

Giorgio Margaritondo, Amela Groso

Broadband synchrotron X-rays with limited coherence can be used for high resolution phase contrast radiology. Our experimental results confirm the prediction that the extreme spatial coherence of third-generation synchrotron sources although helpful but no ...

Digital holography for quantitative phase-contrast imaging

Christian Depeursinge, Etienne Cuche

We present a new application of digital holography for phase- contrast imaging and optical metrology. This holographic imaging technique uses a CCD camera for recording of a digital Fresnel off-axis hologram and a numerical method for hologram reconstructi ...

Simultaneous amplitude-contrast and quantitative phase-contrast microscopy by numerical reconstruction of Fresnel off-axis holograms

Christian Depeursinge, Etienne Cuche, Pierre Marquet

We present a digital method for holographic microscopy involving a CCD camera as a recording device. Off-axis holograms recorded with a magnified image of microscopic objects are numerically reconstructed in amplitude and phase by calculation of scalar dif ...
