Multiple beam ptychography for large field-of-view, high throughput, quantitative phase contrast imaging

•Multiplexing of ptychographic data from coherent beams is presented.•Large field of view imaging from multiple beams with no loss of resolution is demonstrated.•Technique flexibility allows for several experimental configurations.•Proof-of-principle technique is demonstrated using visible wavelengths. The ability to record large field-of-view images without a loss in spatial resolution is of crucial importance for imaging science. For most imaging techniques however, an increase in field-of-view comes at the cost of decreased resolution. Here we present a novel extension to ptychographic coherent diffractive imaging that permits simultaneous full-field imaging of multiple locations by illuminating the sample with spatially separated, interfering probes. This technique allows for large field-of-view imaging in amplitude and phase while maintaining diffraction-limited resolution, without an increase in collected data i.e. diffraction patterns acquired.
