Abstract
An apparatus, system and method are provided to inject an image into a viewing optical system, which is used for viewing a scene. An image injector includes first and second optical elements with first and second sides, respectively, and a reflective material. The first side adjoins the second side and the reflective material is between the adjoining sides. An image generator is optically coupled to the second optical element and generates an image. The image injector is placed at the aperture of the viewing optical system and passes energy from the scene into the viewing optical system. The reflective material reflects energy from the image generator into the viewing optical system. The image generator may produce the image based upon an information signal from an information generator. The reflective material may reflect energy from the scene into an output optical system and the information generator produce the information signal based on the energy received in the output optical system.
