Time-domain vector ptychography

Optics Express
We demonstrate the reconstruction of the instantaneous polarization state of ultrafast laser pulses through vectorial time-domain ptychography. We introduce the formalism, investigate the algorithm’s capacities through simulations, and finally validate it by reconstructing several polarization states from experiments.

Three-dimensional polarimetric ptychography

Optics Express
A three-dimensional polarimetric ptychography (3D-PP) technique is proposed to reconstruct the residual stress distribution in optical elements in three dimensions by combining polarization imaging and a 3D ptychographic iterative engine (3D-PIE).

Near-field ptychography using lateral and longitudinal shifts

New Journal of Physics, 2015
Image reconstruction of in-line holography depends crucially on the probing wave front used to illuminate an object. Aberrations inherent to the illumination can mix with the features imposed by the object.

3D imaging of clay minerals inside sandstone: pushing the spatial resolution limits using ptychographic tomography [PDF]

, 2015
Characterization of microporous, clay-sized particles in natural stone is essential for the understanding of their dynamics. These processes are importand in the fields of oil and gas, groundwater, building stone weathering and soil science. Methods such
