  • Patent number: 4037921
    Abstract: In night vision apparatus, a wide-angle view, and a narrow-angle but higher-resolution view, are observed simultaneously in superposed relationship to provide a composite view which is wide-angle, but has a higher-resolution part. Night vision goggles or binoculars have two optical channels, each with its objective lens system, image intensifier and eyepiece. One of the channels presents a wide-angle view of a scene to one eye and the other channel presents a higher-resolution view of a central portion of the scene to the other eye, both views having the same magnification. A degree of stereoscopy can be obtained in the central portion of the scene even though one eye is only receiving a low resolution view.
