Abstract:
The disclosed apparatus may include a waveguide configuration that may include (1) a coupling area having at least one coupling element configured to receive a plurality of monochromatic images, where each of the monochromatic images is of a predetermined wavelength of light, (2) a propagation area in which light, received via the at least one coupling element, moves within a length of the waveguide configuration, and (3) a decoupling area that extends along the propagation area and includes decoupling elements that project a polychromatic image toward an eyebox, where the polychromatic image includes the monochromatic images of the predetermined wavelengths of light. Associated systems and devices are also provided herein.
