ABSTRACT:
Tracking and sighting apparatus for use in a missile guiding system. The apparatus receives visible light from a target, along with infrared light from the missile itself. Initially a beam splitter separates these different types of light. The beam splitter is followed by separate objectives, one of which is disposed in the path of infrared light and is highly transmissive and suitably refractive to this light, while the other objective is in the path for visible light and is highly transmissive and suitably refractive for this light. The two objectives focus the infrared and visible light, respectively, into a tracking receiver and a sighting ocular.
