Abstract
A sighted device has a sight that includes an objective lens lying on an optical axis of the sight so that an input beam is coincident with the optical axis, an eyepiece lens lying on the optical axis, an imaging detector having a detector output signal, a signal processor that receives the detector output signal from the imaging detector, modifies the detector output signal, and has a processor output signal, and a video display projector that receives the processor output signal and has a video display projector output. An optical beam splitter lies on the optical axis. The beam splitter allows a first split subbeam of the input beam to pass to the eyepiece lens and reflects a second split subbeam of the input beam to the imaging detector. An optical mixer mixes the first split subbeam and the video display projector output prior to the first split subbeam passing through the eyepiece lens.
