Material-resolved and thickness-sensitive lensless imaging using high-harmonic generation: From diffractive shear interferometry to ptychography [PDF]

EPJ Web of Conferences
Microscopy with table-top high-harmonic generation (HHG) sources enable high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-specific absorption edges available in this spectral range.
