Abstract: A near-eye display apparatus for displaying a three-dimensional image to a user. The apparatus includes an image projecting means to project pairs of images associated with different cross-sectional planes of the three-dimensional image; at least one optical display arrangement including a plurality of optical elements, wherein each of the plurality of optical elements is operable to be switched between a first optical state and a second optical state; a control arrangement that is operable to control the at least one optical display arrangement to separately switch each optical element from the first optical state to the second optical state, and the image projecting means to project a separate pair of images on each optical element in the second optical state; and at least one optical device that allows display of the three-dimensional image to each eye of the user.

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.

Abstract: A table-top volumetric display apparatus for presenting three-dimensional imagery.

Abstract: A volumetric display system for displaying a three-dimensional image. The volumetric display system includes a multi-plane volumetric display with display elements; a graphics processing unit to process the aforesaid image to generate image planes corresponding thereto; and a projector communicably coupled to the aforesaid elements. The projector includes a light source for emitting a light beam; a spatial light modulator to modulate the emitted light beam; a telecentric projection arrangement to direct the modulated light beam towards the display elements, whilst providing a substantially-constant magnification of the modulated light beam; and a driver module coupled to the light source, the spatial light modulator. The driver module receives the image planes from the graphics processing unit, and projects the image planes upon the display elements, by way of the modulated light beam.

Abstract: An image display system. The image display system includes an image source for producing an image. The image source includes a plurality of display units arranged in an array and each display unit is configured to emit collimated light for producing a pixel of the image. The image display system includes a volumetric display module including a plurality of optical diffuser elements arranged in a stack. Furthermore, an optical diffuser element of the plurality of optical diffuser elements is maintained in a first state or a second state. The image display system includes a controller operatively coupled to each of the image source and the volumetric display module. The controller is configured to control an optical diffuser element to maintain the optical diffuser element in the second state and the plurality of display units for projecting the image on the optical diffuser element maintained in the second state.
