X-ray-to-visible light-field detection through pixelated colour conversion
Nature, 2023 Light-field detection measures both the intensity of light rays and their precise direction in free space. However, current light-field detection techniques either require complex microlens arrays or are limited to the ultraviolet–visible light ...

Light-field control of real and virtual charge carriers [PDF]
Nature, 2022 Light-driven electronic excitation is a cornerstone for energy and information transfer. In the interaction of intense and ultrafast light fields with solids, electrons may be excited irreversibly, or transiently during illumination only.

UrbanLF: A Comprehensive Light Field Dataset for Semantic Segmentation of Urban Scenes
IEEE transactions on circuits and systems for video technology (Print), 2022 As one of the fundamental technologies for scene understanding, semantic segmentation has been widely explored in the last few years. Light field cameras encode the geometric information by simultaneously recording the spatial information and angular ...

Light-Field Microscopy with a Consumer Light-Field Camera [PDF]
2015 International Conference on 3D Vision, 2015 We explore the use of inexpensive consumer light- field camera technology for the purpose of light-field mi- croscopy. Our experiments are based on the Lytro (first gen- eration) camera. Unfortunately, the optical systems of the Lytro and those of microscopes are not compatible, lead- ing to a loss of light-field information due to angular and spatial ...

Local light field fusion [PDF]
ACM Transactions on Graphics, 2019 We present a practical and robust deep learning solution for capturing and rendering novel views of complex real world scenes for virtual exploration. Previous approaches either require intractably dense view sampling or provide little to no guidance for

Subdiffraction Focusing Metalens Based on the Depletion of Bessel Beams
IEEE Photonics Journal, 2022 Superresolution microscopy is of great interests in modern optics and photonics applications. Subdiffraction focusing lens, that has superresolution focal spot with local spatial frequency greater than the maximum Fourier component, has attracted ...

Quasi light fields: extending the light field to coherent radiation [PDF]
Journal of the Optical Society of America A, 2009 Imaging technologies such as dynamic viewpoint generation are engineered for incoherent radiation using the traditional light field, and for coherent radiation using electromagnetic field theory. We present a model of coherent image formation that strikes a balance between the utility of the light field and the comprehensive predictive power of Maxwell'

Angularly Consistent Light Field Video Interpolation [PDF]
, 2020 International audienceIn this paper, we address the problem of temporal interpolation of sparsely sampled video light fields using dense scene flows. Given light fields at two time instants, the goal is to interpolate an intermediate light field to form ...

Depth estimation and validation of plenoptic light field camera [PDF]
, 2023 A light field (LF) camera can record both the spatial and directional information of light rays in a three-dimensional (3D) scene. This is different from traditional photography, which sums up all the light rays to record their intensity and discard the ...

Ultra-compact snapshot spectral light-field imaging
Nature Communications, 2022 Ideal imaging, which is constantly pursued, requires the collection of all kinds of optical information of the objects in view, such as three-dimensional spatial information (3D) including the planar distribution and depth, and the colors, i.e., spectral
