Abstract:
A head up display includes a light pipe and a waveguide combiner. The light pipe is configured to expand a pupil in a first direction and includes an input grating and an output put grating. The light pipe also includes four elongated surfaces, and the input grating and the output grating are provided in one or more planes parallel to two of the elongated surfaces. The waveguide combiner is configured to expand the pupil in a second direction perpendicular to the first direction. The first light pipe is disposed at an angle with respect to a waveguide combiner.

Claim (Index 14):
A head up display system, comprising:\n at least one light pipe having four elongated surfaces, wherein a first pair of the elongated surfaces are parallel to each other and a second pair of the elongated surfaces are perpendicular to the first pair of the elongated surfaces, wherein light travels through the light pipe in a fashion where the four elongated surfaces are struck by the light as the light travels from a first end to a second end in the first direction; and a waveguide combiner having a main surface for viewing an image and an input grating, the waveguide being disposed such that the first pair of the elongated surfaces are spaced apart from and disposed at an angle with respect to the main surface of the waveguide combiner, wherein the at least one light pipe is configured to expand a pupil in a first direction and provide light to the input grating of the waveguide combiner, the waveguide combiner being configured to expand the pupil in a second direction on the main surface.
