Abstract
There is provided a near-eye device for augmenting a real world view. The near-eye device comprises a spatial light modulator comprising an array of phase modulating elements arranged to apply a phase delay distribution to incident light. The device further comprises a beam combiner comprising a first optical input arranged to receive spatially modulated light from the spatial light modulator and a second optical input having a field of view of the real world.
Claims20
A near-eye device for a user, the near-eye device comprising:
- a spatial light modulator comprising an array of light modulating elements arranged to apply a modulation comprising a phase delay distribution to incident light;
- a light source arranged to illuminate the spatial light modulator with the incident light;
- a beam combiner configured to combine spatially-modulated light from the spatial light modulator received at a first optical input thereof with a field of view of the real world received at a second optical input thereof, the combination providing a combined view in which a holographic image resulting from the spatially-modulated light from the spatial light modulator augments the view of the real world viewed by the user;
- and
- a processor configured to cause the spatial light modulator to modulate the incident light with holographic data representative of an image and with phase data configured to provide eye relief to the holographic image formed by the spatially modulated light.

A method of providing augmented reality to a user, the method comprising:
- providing holographic data representative of an image and phase data;
- spatially modulating light with the holographic data representative of the image and the phase data having the lensing effect to form spatially-modulated light;
- combining the spatially-modulated light with a field of view of the real world using a beam combiner to provide combined view in which a holographic image resulting from the spatially-modulated light from the spatial light modulator augments the view of the real world;
- and
- providing the combined view to the user's eye.
- wherein the phase data is configured to provide eye relief to the holographic image formed by the spatially-modulated light.
