Abstract
A holographic optical system includes a hologram which is located at an instrument panel so as to reflect or transmit an image from a source located off the panel. The image is redirected 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 such as where the instrument panel is within an aircraft cockpit.
