TLDR
In this paper, a spatio-temporal directional light modulator is introduced to modulate the intensity, color and direction of the light it emits within an wide viewing angle.Abstract:
A spatio-temporal directional light modulator is introduced This directional light modulator can be used to create 3D displays, ultra-high resolution 2D displays or 2D/3D switchable displays with extended viewing angle The spatio-temporal aspects of this novel light modulator allow it to modulate the intensity, color and direction of the light it emits within an wide viewing angle The inherently fast modulation and wide angular coverage capabilities of this directional light modulator increase the achievable viewing angle, and directional resolution making the 3D images created by the display be more realistic or alternatively the 2D images created by the display having ultra high resolutionread more

Spatio-temporal light field cameras
Hussein S. El-Ghoroury,Zahir Y. Alpaslan,Jingbo Cai,Marty Maiers,Philip Warner,Dale A. McNeill +5 more
TL;DR: Spatio-temporal light field cameras as mentioned in this paper can be used to capture the light field within its spatio temporally extended angular extent, which can capture and digitally record the intensity and color from multiple directional views within a wide angle.

Methods for Full Parallax Compressed Light Field 3D Imaging Systems
TL;DR: In this article, a compressed light field imaging system is described, where the light field 3D data is analyzed to determine optimal subset of light field samples to be (acquired) rendered, while the remaining samples are generated using multi-reference depth-image based rendering.

Dual-mode augmented/virtual reality (ar/vr) near-eye wearable displays
TL;DR: In this article, a dual-mode augmented/virtual reality near-eye wearable display for use with a curved lens element is presented, where a plurality of image sources are disposed on the peripheral surface of the lenses whereby each image source has a dedicated input image aperture and exit aperture subregion that are each piecewise flat and have matched areas and angles of divergence.

Light field photography with a hand-held plenoptic camera
TL;DR: The plenoptic camera as mentioned in this paper uses a microlens array between the sensor and the main lens to measure the total amount of light deposited at that location, but how much light arrives along each ray.

Single lens stereo with a plenoptic camera
Edward H. Adelson,J.Y.A. Wang +1 more
TL;DR: The authors describe a camera for performing single lens stereo analysis, which incorporates a single main lens along with a lenticular array placed at the sensor plane and extracts information about both horizontal and vertical parallax, which improves the reliability of the depth estimates.

Epipolar-plane image analysis: An approach to determining structure from motion
TL;DR: This article describes the application of a technique for building a three-dimensional description of a static scene from a dense sequence of images, and shows how projective duality is used to extend the analysis to a wider class of camera motions and object types that include curved and moving objects.

Uniform illumination system
Robert L. Holman,Arthur Cox +1 more
TL;DR: In this article, a planar multi-layered LED light source arrays concentrating their polarized or unpolarized output within a limited angular range are presented. But the optical interaction between light emitters, reflecting sidewalls and the elevated prismatic films create overlapping virtual images between emitting regions that contribute to the greater optical uniformity.

TL;DR: In this paper, the authors present a unified solution to focus problems by instead recording the light field inside the camera: not just the position but also the direction of light rays striking the image plane.
