Abstract

A windshield for a head-up display system has a pair of opposing major surfaces that are nonparallel to one another either throughout its extent or in selected areas. Light rays directed toward the nonparallel area of the windshield are reflected from the outer and inner major surfaces of the windshield and directed toward the eye of the observer as parallel or superimposed light rays to eliminate ghost images when viewing images projected by the head-up display system through the windshield.
