MICROLENS COLLIMATOR FOR SCANNING OPTICAL FIBER IN VIRTUAL/AUGMENTED REALITY SYSTEM

摘要

A display subsystem for a virtual image generation system for use by an end user comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a collimation element mounted to a distal end of the optical fiber for collimating light from the optical fiber. The virtual image generation system further comprises a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the distal end of the optical fiber, along with the collimation element, in accordance with a scan pattern. The virtual image generation system further comprises an optical waveguide input apparatus configured for directing the collimated light from the collimation element down the planar waveguide apparatus, such that the planar waveguide apparatus displays image frames to the end user.
