Abstract

High frame rate (HFR) phase-and-amplitude contrast imaging is imperative for a better understanding of the underlying physics in dynamically evolving phenomena. Here we present, to our knowledge, the first experimental HFR ptychographic reconstructions using a novel Time-Resolved Imaging via Multiplexed Ptychography (TIMP) system. Our TIMP system is composed of a time-encoding device, which creates a train of temporally separated pulses of different phase profiles, and a novel beam-sampling single-shot ptychography microscope. HFR imaging is achieved by reconstructing the complex object from each pulse independently and time ordering the reconstructed objects based on the phase structure of the reconstructed probes.
