Abstract
Light re-reflection in a picture generation unit for a heads up display is reduced by a housing having walls that are 'surfaced' to have inclined surfaces, which reflect light incident upon them toward inclined surfaces on a second and opposing surfaced wall. Re-reflections of light off the surfaced sidewalls attenuates light to a degree that it cannot generate a visible image.
