Autostereoscopic display device
TL;DR: An auto stereoscopic 3D display consisting of a hybrid sandwich comprising a first lenticular screen, a spatial light modulator, a diffuser, and second Lenticular screen is described in this paper.

Parallax barrier, display, passive polarisation modulating optical element and method of making such an element
Robert Mosley Richard,John Woodgate Graham,Adrian Marc Simon Jacobs,Jonathan Harrold,David Ezra +4 more
TL;DR: A parallax barrier as discussed by the authors includes a polarisation modifying layer having aperture regions, separated by barrier regions, for supplying light of a third polarisation different from the second polarisation when receiving light of the first polarisation, and a polariser selectively operable in a first and a second mode.

Controlling perceived depth in stereoscopic images
TL;DR: A novel method for calculating stereoscopic camera parameters is described, which provides the user intuitive controls related to easily measured physical values and precisely controlled perceived depth, and a new analysis of the distortions introduced by different camera parameters was undertaken.

Display for 3D images
David Ezra,Graham John Woodgate +1 more
TL;DR: A tracking system tracks the position of an observer and a control system controls the positions of the light sources (2a,2b) so that the images formed by the lenses (3a,3b) or mirrors track the observer as mentioned in this paper.
Patent
Observer tracking directional display
TL;DR: An observer tracking directional display comprises a spatial light modulator associated with a movable parallax optic as discussed by the authors, which determines the position of an observer by way of an electromechanical transducer and a mechanical transmission.
