TL;DR: The Variational Hilbert Quantitative Phase Imaging (VHQPI) is proposed—end-to-end purely computational add-on module able to improve performance of a QPI-unit without hardware modifications, potentially opening up new possibilities in QPI.

TL;DR: In this article, an adaptive filtering of the recorded on-axis hologram to eliminate its background term and extract interference intensity component connected with light scattered on the sample (interference fringes) is proposed.

TL;DR: An automated adaptive optics solution is applied to correct the performance of both STED masks, enhancing robustness and expanding the capabilities of this nanoscopic technique.

TL;DR: The proposed π-SMIM equips a commercially available nonholographic microscope with a high-speed (video frame rate) enhanced quantitative phase imaging (QPI) capability by properly placing a beam-splitter in the microscope embodiment to simultaneously record two holograms mutually phase shifted by π radians at the expense of reducing the field of view.

TL;DR: In this paper, a wide-angle registration and display of digital holograms of static 3D scenes is presented, which combines Fourier holography with the synthetic aperture technique, which results in recording performance of a wide spherically curved detector.
