Diffractive optics can be used to accurately control optical wavefronts, even in situations
where refractive components such as lenses are not available. For instance, conventional …

Imaging large areas of a sample non-destructively and with high resolution is of great
interest for both science and industry. For scanning coherent X-ray diffraction microscopy, ie …

Optical metasurfaces are optical components composed of a set of nanostructures that
interact strongly with light, thus considerably modifying its properties over a thickness …

Lensless imaging techniques such as ptychography have revolutionized short-wavelength
metrology by enabling photon-efficient, diffraction limited, robust phase-contrast imaging of …
