Well-known light-field (LF) optics are currently being exploited in many so-called LF (or plenoptic) cameras, i.e., a special kind of camera with which the focal conditions of the pictures can be altered after they have been obtained. The 2D images can then be generated by sectioning the acquired data at a specific selected point.1 Given this capability, it should also theoretically be possible to reconstruct the original 3D scene from the 2D data. Such 3D reconstructions, however, have not previously been realized. Moreover, the most common methods for 3D display are stereoscopic or multiview displays.  Read More
