Mode purity and structural analysis of x-ray vortices generated by spiral zone plates
M. Baluktsian, L. Loetgering, G. Dogan +6
In the visible spectrum vortex beams have found various applications, ranging from optical tweezers to super-resolution imaging. Recently, these beams have been demonstrated using…
Maskless off-axis X-ray Holography
Kahraman Keskinbora, Abraham Levitan, Gisela Schütz +1
Off-axis X-ray holography is a lensless imaging technique that allows unambiguous retrieval of an object's exit-wave function with high fidelity. It has been used with great succes…
Single-frame far-field diffractive imaging with randomized illumination
Abraham L. Levitan, Kahraman Keskinbora, Umut T. Sanli +2
We introduce a single-frame diffractive imaging method called randomized probe imaging (RPI). In RPI, a sample is illuminated by a structured probe field containing speckles smalle…
