Seminarium Optyczne

Ptychography is a label-free phase imaging technique that revolutionized microscopy in spectral domains where high-quality lenses are challenging to come by, including x-rays, extreme ultraviolet, terahertz radiation and electrons. In recent years, related techniques have emerged that utilize ptychography for visible light microscopes, optical diffraction tomography and high throughput whole slide imaging. In my talk, I will give an overview of the several flavors of ptychography and highlight applications from tabletop extreme ultraviolet lensless imaging using high harmonic generation. The goal of this talk is to provide an introduction of what ptychography is and what it is good for.
