Patent ID: 8666212

Claim:
An optical apparatus of a head mounted display, the optical apparatus comprising: a fused fiber bundle including an array of fused optical fibers having an in-coupling surface located at a first end for receiving a light image and an out-coupling surface physically facing an eye-ward direction and located at a second end for emitting the light image, wherein the fused fiber bundle is tapered such that the in-coupling surface has a larger surface area than the out-coupling surface to compress the light image and individual fiber diameters within the fused fiber bundle have smaller cross-sections at the out-coupling surface relative to the in-coupling surface; an image source for generating the light image, the image source disposed at the first end of the fused fiber bundle and optically aligned with the in-coupling surface to launch the light image into the fused fiber bundle; an image lens disposed at the second end of the fused fiber bundle and optically aligned with the out-coupling surface to focus the light image emitted from the second end towards an eye when the head mounted display is worn; and a glasses structure, including: a lens region positioned to align with the eye of a user when the glasses structure is worn by the user; and an ear member coupled to the lens region and shaped to be supported by an ear of the user when worn by the user, wherein the image source is mounted to the ear member and the fused fiber bundle extends from the image source to a central location within the lens region, the central location aligned with the eye of the user when the glasses structure is worn by the user.
