Methods and systems are for aligning a light projection engine (e.g., in a virtual reality headset) are described. An assembly for aligning the light projection engine includes a frame, an optical waveguide assembly; and the light projection engine. Embodiments include assemblies for aligning based on a pivot point, an optical axis, an X, a Y, and a Z axis, and with six degrees of freedom. In addition, an embodiment includes three planar joints that allow for alignment of the light projection engine.

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.
