Abstract
Disclosed is volumetric display arrangement for representing content of an image at different focal distances in a view of real-world environment. The volumetric display arrangement includes at least one image projection unit operable to project multiple depth planes of the image, at least one electro-optical unit comprising two or more optical diffuser elements arranged parallel to each other, the at least one electro-optical unit being positioned to receive the projected multiple depth planes of the image thereon and configured to independently display one of the projected multiple depth planes of the image at one of the two or more optical diffuser elements at a given instant of time, and an optical combiner positioned with respect to the at least one electro-optical unit to combine the view of real-world environment with the independently displayed multiple depth planes of the image in the at least one electro-optical unit.
