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 1):
A head up display, comprising:\n a light pipe configured to expand a pupil in a first direction, the light pipe comprising four elongated surfaces comprising at least two elongated surfaces that are parallel to each other, wherein the light pipe is configured so that 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 in optical communication with the light pipe and comprising a main surface disposed at an angle with respect to the two parallel elongated surfaces, the waveguide combiner being configured to expand the pupil in a second direction along the main surface.
