Abstract
A multi-view display system or optical vortex 3D display in a multi-view or multilayer embodiment or configuration. The new 3D display system encodes and decodes images into independent modes of optical angular momentum (OAM). In some embodiments, the 3D display system uses pixel-based OAM. In such systems, transformation optics are used to sort the OAM modes. These transformation optics convert the OAMs' spiral wavefronts to linear gradient wavefronts, which are then deflected by a simple lens. The transformation optics, thus, are used in image-based (per pixel) decoding/sorting. In other embodiments, the 3D display system uses image-based OAM. In such systems, convolution of the OAM modes with the image is used rather than the direct modulation of the OAM mode and the image (as used in the prior system discussed above) for image-based encoding and decoding/sorting of images in different OAM modes.
