Abstract
Soft-x-ray digital in-line microscopic holography is achieved using a fully coherent high-order harmonic source emitting at . Combination of commercial-grade soft-x-ray optics and a back-illuminated CCD detector allows a compact and versatile holographic setup. Different experimental geometries have been tested by imaging calibrated tips and wires. Spatial resolution of is measured with magnifications ranging from 30 to 110 and a numerical aperture around 0.01. Finally, the potentiality of three-dimensional numerical reconstruction from a single hologram acquisition is shown experimentally.
