  • Patent number: 12270999
    Abstract: A method and system for increasing dynamic digitized wavefront resolution, i.e., the density of output beamlets, can include receiving a single collimated source light beam and producing multiple output beamlets spatially offset when out-coupled from a waveguide. The multiple output beamlets can be obtained by offsetting and replicating a collimated source light beam. Alternatively, the multiple output beamlets can be obtained by using a collimated incoming source light beam having multiple input beams with different wavelengths in the vicinity of the nominal wavelength of a particular color. The collimated incoming source light beam can be in-coupled into the eyepiece designed for the nominal wavelength. The input beams with multiple wavelengths take different paths when they undergo total internal reflection in the waveguide, which produces multiple output beamlets.
