PoreSpy: A Python Toolkit for Quantitative Analysis of Porous Media Images (2019, methodology): “A variety of techniques are available for imaging a material’s internal pore structure with sub-micron resolution, including X-ray tomography (Coles et al., 1998), ptychography (Dierolf et al., 2010), and FIB-SEM sectioning (Heaney, Vicenzi, Giannuzzi, & Livi, 2001).”
Phase Retrieval with Application to Optical Imaging: A contemporary overview (2015, methodology): “However, notwithstanding these challenges, successful phase retrieval of experimental data in optical imaging has been widely achieved [3], [13], [16], [17], [23], [28], [80], [119], [120].”
Imaging without lenses: achievements and remaining challenges of wide-field on-chip microscopy (2012, background): “…that the ability of lens-free in-line holography to digitally propagate a field over a long depth of focus does not immediately permit tomographic imaging of objects unless multiangle illumination 13,14 , ptychographic tomography 51 or a compressive holography–based approach 15,52 is used.”
Coherent X-Ray Diffraction Imaging (2012, background): “CDI [31], [32], [42], [44], in which a circular aperture or focusing optics is used to define an illumination probe.”
