Abstract:
A near-eye display device comprises a pupil-expansion optic, first and second lasers, a drive circuit coupled operatively to the first and second lasers, a beam combiner, a spatial light modulator (SLM), and a computer. The first and second lasers are configured to emit in respective first and second wavelength bands. The beam combiner is configured to geometrically combine emission from the first and second lasers into a collimated beam. The SLM is configured to receive the collimated beam and to direct the emission in spatially modulated form to the pupil-expansion optic. The computer is configured to parse a digital image, trigger the emission from the first and second lasers by causing the drive circuit to drive current through the first and second lasers, and control the SLM such that the spatially modulated form of the emission projects an optical image corresponding to the digital image.
