Abstract
A system and method for introducing a display image into an afocal optics device through an objective lens and without using a beamsplitter. A display device emits the image in a first direction, a focusing lens focuses the image, and a first reflector redirects the image in a second direction. A second reflector redirects the image through a periphery of the lens so that both the image and gathered light received from a target appears on the same focal plane such that the image appears to a user to be located between the lens and the target. The periphery of the objective lens may be a distance which is no more than 30% of a diameter of the lens from an edge of the lens. If the optics device is a rifle scope, the image may communicate such relevant information as range, inclination, wind direction or velocity, or temperature.
