recommendations! Published in 2022 at "Journal of Biophotonics"

DOI: 10.1002/jbio.202200240

Abstract: Fourier ptychographic microscopy (FPM) is a promising super‐resolution computational imaging technology. It stitches a series of low‐resolution (LR) images in the Fourier domain by an iterative method. Thus, it obtains a large field of view… read more here.

DOI: 10.1016/j.optcom.2020.125764

Abstract: Abstract It is inherently difficult for a conventional microscopic imaging system to produce images with both wide field of view (FOV) and high-resolution because of its limited space bandwidth product. Fourier ptychographic microscopy (FPM) has… read more here.

DOI: 10.1016/j.optlaseng.2020.106410

Abstract: Abstract We present a novel microscopy concept, termed Multi-Aperture Fourier ptychographic microscopy (MA-FPM), to enable implementation of parallel detectors in microscopy to increase the space-bandwidth-time product. MA-FPM is a synthetic aperture technique: an array of… read more here.
