Abstract
An optical apparatus of a head mounted display includes a fused fiber bundle, an image source, and an image lens. The fused fiber bundle includes an array of fused optical fibers having an in-coupling surface located at a first end and an out-coupling surface physically facing an eye-ward direction and located at a second end. 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. The image source is 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. The image lens is disposed at the second end 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.
