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: Displaying a sequence of three-dimensional images includes generating a data stream including a plurality of image planes associated with each image of the sequence of three-dimensional images, generating a bit-plane stream associated with the data stream, the bit-plane stream including a plurality of bit-planes associated with each image of the sequence of three-dimensional images, buffering the bit-plane stream asynchronously to provide a first plurality of bit-planes associated with a first three-dimensional image, and projecting a first plurality of image planes associated with the first three-dimensional image to display the first three-dimensional image, based upon the first plurality of bit-planes, the first plurality of image planes being projected until a second plurality of bit-planes associated with a second three-dimensional image is provided.

Abstract: There is disclosed an optical display arrangement. The optical display arrangement includes an optical element, a voltage source connected to the optical element and a controller operatively coupled to the voltage source. The controller is operable to control the voltage source to apply a first voltage pulse over an operating voltage for a first period of time, to the optical element, to switch the optical element from a first optical state to a second optical state wherein the first voltage pulse is a sum of elevated voltage and operating voltage. Furthermore, the controller is operable to provide the operating voltage to the optical element to maintain the optical element in the second optical state. Moreover, the controller is operable to remove the operating voltage from the optical element to switch the optical element from the second optical state to the first optical state.
