Abstract
A display assembly suitable for use with a virtual or augmented reality headset is described and includes the following: an input coupling grating; a scanning mirror configured to rotate about two or more different axes of rotation; an optical element; and optical fibers, each of which have a light emitting end disposed between the input coupling grating and the scanning mirror and oriented such that light emitted from the light emitting end is refracted through at least a portion of the optical element, reflected off the scanning mirror, refracted back through the optical element and into the input coupling grating. The scanning mirror can be built upon a MEMS type architecture.
