AVOIDING INTERFERENCE BY REDUCING SPATIAL COHERENCE IN A NEAR-EYE DISPLAY

摘要

Disclosed are an apparatus and method for reducing interference for a near-eye display device. The near-eye display device includes an imager, a spatial light modulator and a waveguide. The imager generates an image based on light from a coherent light source. The spatial light modulator modulates phases of a plurality of coherent light rays representing the image received from the imager. The waveguide receives and guides the light rays having varied phases such that light rays propagating within the waveguide are incoherent with each other.
