RPA for Light-Front Hamiltonian Field Theory [PDF]
, 1999 A self-consistent random phase approximation (RPA) is proposed as an effective Hamiltonian method in Light-Front Field Theory (LFFT). We apply the general idea to the light-front massive Schwinger model to obtain a new bound state equation and solve it ...

Light-Field Imaging and Heterogeneous Light Fields [PDF]
, 2016 In traditional light-field analysis, images have matched spectral content which leads to constant intensity on epipolar plane image (EPI) manifolds. This kind of light field is termed homogeneous light field}. Heterogeneous light fields differ in that contributing images may have varying properties such as exposure selected or color filter applied. To

What Do Forbidden Light-ray Fields Look Like? [PDF]
, 2014 Ray-optically, optical components change a light-ray field on a surface immediately in front of the component into a different light-ray field on a surface behind the component.

CoRR, 2019 Most computer vision systems and computational photography systems are visible light based which is a small fraction of the electromagnetic (EM) spectrum. In recent years radio frequency (RF) hardware has become more widely available, for example, many cars are equipped with a RADAR, and almost every home has a WiFi device.

A Vignetting Model for Light Field Cameras With an Application to Light Field Microscopy [PDF]
IEEE Transactions on Computational Imaging, 2019 In standard photography, vignetting is considered mainly as a radiometric effect because it results in a darkening of the edges of the captured image. In this paper, we demonstrate that for light field cameras, vignetting is more than just a radio-metric effect.
