Volumetric particle image velocimetry with a single plenoptic camera (2015, unknown): “Of the more recent developments we particularly note the work of Ng [25, 26], who designed a hand-held plenoptic camera for digital photography.”

Dappled photography: mask enhanced cameras for heterodyned light fields and coded aperture refocusing (2007, methodology): “To further combat the effects of aliasing, we post-filter the recovered light field using a Kaiser-Bessel filter with a filter width of 1.5 [Ng 2005].”
3D intensity and phase imaging from light field measurements in an LED array microscope (2015, background): “Thus, light fields describe 4D data that can be thought of as limited-angle tomography with multiple directions of rotation [31,32].”
Decoding, Calibration and Rectification for Lenselet-Based Plenoptic Cameras (2013, background): “With increased depth of field and light gathering relative to conventional cameras, and post-capture capabilities ranging from refocus to occlusion removal and closed-form visual odometry [1, 16, 4, 9, 19, 6], plenoptic cameras are poised to play a significant role in computer vision applications.”
Pushing the Boundaries of View Extrapolation With Multiplane Images (2019, methodology): “We apply the generalized Fourier slice theorem [19] to interpret the Fourier transform of this integral projection as a 2D slice through the 3D MPI’s Fourier transform.”
Compressive light field photography using overcomplete dictionaries and optimized projections (2013, background): “Based on recent insights, such as the dimensionality gap [Ng 2005; Levin et al. 2009], one would expect that the increased dimensionality from 2D images to 4D light fields introduces a lot of redundancy.”
Light field microscopy (2006, methodology): “Spurred by improvements in the technology for manufacturing microlenses (smaller than 1mm), researchers have proposed using arrays of them for computer vision [Adelson 1992], 3D video [Javidi 2002], and photography [Ng et al. 2005].”
