Claim 0:
1. A method for rendering a virtual image with a virtual image generation system, comprising:
emitting light from a distal end of an optical fiber in the virtual image generation system, wherein the optical fiber comprises a longitudinal direction in a nominal position and is driven to vibrate in one or more scan patterns about a fulcrum along the longitudinal direction;
collimating the light emitted from the distal end of the optical fiber into collimated light in a direction proximate to the longitudinal direction using at least a collimation element having a single lens;
receiving the collimated light at a waveguide apparatus of the virtual image generation system;
generating a stereoscopic virtual image at least by diffracting the collimated light at a plurality of focal depths with at least an optical diffractive element in the waveguide apparatus; and
generating diverged light, which diverges from the longitudinal direction, from the light emitted from the distal end of the optical fiber at least by driving, using a drive assembly of the virtual image generation system, at least the distal end of the optical fiber according to a scan pattern of the one or more scan patterns,
wherein the diverged light is generated in a plurality of off-axis directions that deviates from the longitudinal direction when the optical fiber is in the nominal position.
