Abstract
A holographic center high mounted stoplight system that includes a light source for providing a nearly collimated beam, an expanding lens responsive to the nearly collimated beam for providing a diverging or converging reconstruction beam, and a stoplight hologram responsive to the expanding beam for producing stoplight illumination. Also disclosed is a holographic center high mounted stoplight system that includes a light source for providing a nearly collimated beam, a light bending hologram for providing a diffracted near collimated beam, and an expanding stoplight lens array responsive to the diffracted near collimated beam for providing non-collimated stoplight illumination.
