Motion-corrected Fourier ptychography

Biomedical Optics Express, 2016
Fourier ptychography (FP) is a recently proposed computational imaging technique for high space-bandwidth product imaging. In real setups such as endoscope and transmission electron microscope, the common sample motion largely degrades the FP reconstruction and limits its practicability.

Mapping biological composition through quantitative phase and absorption X-ray ptychography

, 2014
Isolating compositional information in biological X-ray imaging can be problematic as such information is conflated with thickness and density variations when viewing in projection through a sample.
