Waveguide assembly and alignment design and integration

Abstract:

Methods and systems are provided to assemble an optical waveguide assembly. An optical waveguide assembly may be used in a virtual reality headset or other type of projection system. The optical waveguide assembly includes a front lens, one or more optical waveguides, and a back lens. In one embodiment, an insert is used that is the same width as the optical waveguides to prevent cracking of the optical waveguides. In another embodiment, the optical waveguide assembly includes Optically Clear Adhesive (OCA) tape between the different elements of the optical waveguide assembly to precisely align the optical waveguides. In another embodiment, the optical waveguide assembly has cover portions or a frame that protect the optical waveguides in the optical waveguide assembly.
