Abstract:
1. 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:
