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 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;
- and
- a processor configured to cause the spatial light modulator to modulate the incident light with phase data having a negative lensing effect and with holographic data representative of an image, wherein the lensing effect is such that the spatially modulated light received from the spatial light modulator by the beam combiner is diverging.

A method of providing augmented reality using a near-eye device, the method comprising:
- providing holographic data representative of an image and phase data having a lensing effect;
- 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;
- and
- providing the combined spatially-modulated light to a user's eye,
- wherein the lensing effect is negative such that the spatially modulated light received from the spatial light modulator by the beam combined is diverging.
