Abstract
A windshield display system for automobile includes a wavelength selective holographic combiner (12) laminated within the plies (36, 50) of an automobile windshield. A lamination process is provided to prevent degradation of the holographic combiner (12), which might otherwise occur with conventional windshield lamination processes. The holographic combiner (12) is processed in a manner that permits it to withstand the temperature and pressure extremes of the windshield lamination process. Also provided is a display system (60) for producing an image of vehicle information and the motorist's field of view as the motorist observes the real world scene.
