Femtosecond time-delay X-ray holography

Single-shot femtosecond x-ray holography using extended references.

In the context of x-ray lensless imaging, we present a recent approach for Fourier transform holography based on the use of extended references. Major advances shown here rely on a high signal efficiency and on the direct image reconstruction of the object performed by a simple linear derivative. Moreover, the extended holographic reference is easy to manufacture and can be applied to a variety...

X-ray holography: theory and experiment

A detailed description of x-ray fluorescent holography is given using the formalism of classical electrodynamics. Effects of the wavefront curvature are calculated. It is shown that neglecting these effects might cause large errors especially in the forward direction. The model calculation is compared with experimental data. It is shown that for the model system of NiO the experiment agrees wel...

A modern approach to x-ray holography

We consider technical approaches to the problem of making 3-D images of large (>10 μm) life-science samples with about 10 nm resolution . We find no existing methods and discuss the possibility of using soft x-ray diffractive techniques especially holography. We propose a new form of Fourier transform x-ray holography using a reference object consisting of an array of small pinholes formed by e...
