Abstract
A holographic display comprises: an illumination source which is at least partially coherent; a plurality of display elements positioned to receive light from the illumination source and spaced apart from each other, each display element comprising a group of at least two sub-elements; and a modulation system associated with each display element and configured to modulate at least a phase of each of the plurality of sub-elements.
Claims20
A holographic display comprising:
- an illumination source which is at least partially coherent;
- a plurality of display elements positioned to receive light from the illumination source and spaced apart from each other, each display element comprising a group of at least two sub-elements;
- and
- a modulation system associated with each display element and configured to modulate at least a phase of each of the plurality of sub-elements.
1 more element
An apparatus comprising:
- a holographic display according to any preceding claim;
- and
- a controller for controlling the modulation system such that each display element has a first amplitude and phase when viewed from a first position and a second amplitude and phase when viewed from a second position.
A method of displaying a computer-generated hologram, the method comprising:
- controlling a phase of a plurality of groups of sub-elements such that the output of sub-elements within each group combines to produce a respective first amplitude and a first phase at a first viewing position and a respective second amplitude and a second phase at a second viewing position.
