Abstract
A holographic optical element is applied over existing aircraft panel and instruments thereon so as to display an image which is reflected from a source located off the panel. The image is reflected only to an area at which the viewer may observe the image and is not directed to other areas so as to prevent unwanted reflections and glare within the aircraft cockpit.
