ABSTRACT:
A substantially ghost-free head-up display for a vehicle such as an automobile is disclosed. A head-up display unit projects the image beam toward the vehicle windshield for reflection back toward the viewer's eye. The windshield is slightly tapered so that the reflected images from the outside and inside surfaces of the windshield are reflected at slightly different angles, chosen so that the images substantially overlap at the viewer's eye. Use of a properly selected taper results in substantially ghost-free operation. The taper can be achieved by sandwiching a tapered layer of transparent material such as polyvinylbutyral between two windshield singlets.
