Abstract
Device for combining a scene image, produced by an imaging system, with an induced image, the imaging system including an eyepiece optics and at least a display screen producing the scene image, the eyepiece optics being located between the display screen and the eye of the observer, the device including an optical director projecting the induced image toward a diffusive surface, the diffusive surface being located between the display screen and the eyepiece optics, wherein the diffusive surface reflects the induced image back, toward the observer, through the eyepiece optics, and wherein the diffusive surface transmits the scene image from the display screen toward the observer, through the eyepiece optics.
