Phase Retrieval via Matrix Completion (2011, background): “Here, one measures multiple diffraction patterns by scanning a finite illumination on an extended specimen [66, 69].”
Tabletop nanometer extreme ultraviolet imaging in an extended reflection mode using coherent Fresnel ptychography (2013, methodology): “The positions were randomized by up to 1 μm in order to prevent periodic artifacts from occurring in the ptychographic reconstruction[18].”
Computational illumination for high-speed in vitro Fourier ptychographic microscopy (2015, neutral): “Distinct from synthetic aperture, FPM does not measure phase directly at each angle, but instead uses nonlinear optimization algorithms [7, 15–17] similar to translational diversity [18, 19] and ptychography [20, 21].”
3D intensity and phase imaging from light field measurements in an LED array microscope (2015, methodology): “The caveat is that phase is required, which the Fourier ptychography algorithm [23,24] provides by performing translational diversity phase retrieval [43–46] in Fourier space.”
Experimental robustness of Fourier Ptychography phase retrieval algorithms (2015, result): “There are already more sophisticated FPM extensions to correct for some model mis-match errors [18, 19], similar to the probe correction algorithms in traditional ptychography [16].”
Phase Retrieval from Coded Diffraction Patterns (2013, positive): “There are several ways of achieving modulations of this type: one can use a phase mask just after the sample, see Figure 1, or use an optical grating to modulate the illumination beam as mentioned in [37], or even use techniques from ptychography which scan an illumination patch on an extended speci”
Coherent methods in the X-ray sciences (2009, methodology): “The algorithms have been shown to be able to fit the entire diffraction pattern, to recover the probe through the iterative method, and to allow the high resolution imaging of structures below the surface [233] and able to simultaneously recover the wavefront of the illuminating beam [234], allowing”
Subwavelength coherent imaging of periodic samples using a 13.5 nm tabletop high-harmonic light source (2017, methodology): “To prevent periodic artifacts being introduced by the scan grid itself, a random offset of ±20% of the step size is added to each scan position 41 .”
An improved ptychographical phase retrieval algorithm for diffractive imaging. (2009, methodology): “Once the constraint sets have been defined, various strategies based on alternating projections can be used to find their intersection [16]—in [13,15] the ‘difference map’ method is used, which is similar to a relaxed version of Fienup’s hybrid input–output method.”
