Light projection engine attachment and alignment

Abstract:

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.
