Abstract
An auto stereoscopic 3D display comprises a hybrid sandwich comprising a first lenticular screen, a spatial light modulator, a diffuser, and second lenticular screen. A plurality of light sources produce in turn divergent light beams which are modulated by the modulator with two interlaced views. The hybrid sandwich projects the views in different directions towards an observer. The different 2D views are thus visible from directions corresponding to the directions in which the views were captured during recording of a 3D image. Each eye of the observer sees a single view across the whole of the display.
Claims21
A display for producing an autostereoscopic image, comprising:
- at least one light source for producing a divergent beam of light;
- a spatial light modulator comprising a plurality of light modulating cells for modulating light passing therethrough from the at least one light source in accordance with image data;
- a first array of optical components arranged to receive the divergent light beam from the at least one light source, each of the optical components being arranged to produce an image of the at least one source at a common image plane such that each image is laterally displaced by a respective predetermined amount from an optical axis of the corresponding optical component and the respective predetermined amounts vary progressively across the common image plane;
- and
- a second array of optical components having a common object plane which coincides with the common image plane.
