Abstract: Systems of the present disclosure may include one or more of an optical overlay device, which may include one or more of an imaging optic to receive incoming light from a scene, and project at least a portion of the incoming light onto an imaging sensor; an imaging sensor to transduce into image data the light projected onto it by the imaging optic; a processing engine electrically coupled with a non-transitory computer readable medium having machine readable instructions stored thereon, which, when executed by the processing engine, cause the system to: generate a scaled overlay image based on the image data and a magnification parameter; a display device configured to project the scaled overlay image through a display optic toward a portion of a beam-combiner; a coupling mechanism to enable releasable attachment of the optical overlay device with a primary viewing device.
