Single-shot ptychography & sparsity-based subwavelength ptychography

Not Accessible

Your library or personal account may give you access

Abstract

We overcome two major limitations in ptychography – a powerful scanning-based coherent diffraction imaging technique. We demonstrate single-shot ptychography, overcoming the scanning-limited temporal resolution and also demonstrate sparsity-based subwavelength ptychography, overcoming the Abbe spatial resolution limit.
