Patent ID: 7911687

Claim:
A sight for mounting on a weapon, the sight comprising: a housing for affixing directly to the weapon; an objective lens system mounted to the housing for receiving a pictorial image of a distant target on an input beam and for establishing an optical axis; an eyepiece lens system mounted to the housing and located to be adjacent a user's eye in use and aligned on the optical axis; a single, integrated beam splitter/mixer structure disposed between the objective lens system and the eyepiece lens system in the housing for passing an electronically unprocessed visible image of the target to the eyepiece lens system along the optical axis, for also reflecting the pictorial image of the target away from the optical axis, for optically mixing the passing unprocessed visible image and an electronically processed image of the reflected image, and for outputting the optically mixed images to the eyepiece lens system along the optical axis; an image detector for receiving the reflected image and for generating a signal responsive to the reflected image; a signal processor for receiving the signal responsive to the reflected image, for electronically modifying the reflected image and for generating an output signal responsive to the modified reflected image; and a video display projector for receiving the output signal from the signal processor and for projecting a video display responsive to the signal processor output signal, wherein should there be a failure of the image detector, the signal processor and/or the video display, passing of the unprocessed visible image of the target to the eyepiece lens system along the optical axis remains undisturbed.
