Abstract
A method of displaying an image to a viewer includes operating a fiber scanning projector to produce a scanned light beam incident on an incoupling diffractive optical element (DOE) coupled to a waveguide. A portion of the light beam is reflected via a reflective back surface of the incoupling DOE. The reflected portion of the scanned light beam is incident on a reflective optical element, which reflects the light beam back to the incoupling DOE. The returning light beam is then diffracted by the incoupling DOE to produce a second pass first diffracted light beam. The second pass first diffracted light beam is propagated within the planar waveguide via total internal reflection (TIR) to an outcoupling DOE, which directs a portion of the second pass first diffracted light beam toward an eye of a viewer to display the image to the user.
