Paper Abstract

The holographic center high mounted stoplight achieves the required performance of a conventional center high mounted stoplight, but without the obstruction to the driver's view through the rear window. A lamp located in the roof illuminates a transmission image hologram mounted on the inner surface of the automobile rear window. The hologram strongly diffracts the incident light rearward but is transparent to the driver looking in his rearview mirror.
