  • Viewing apparatus capable of moving a subject within the field of view of the center of the viewed image
    Patent number: 8294080
    Abstract: A viewing apparatus comprises one or more optical elements, which may be moved in order to redirect light entering the viewing apparatus such that a subject in any part of the field of view may be relocated to the center of the viewed image without moving the viewing apparatus itself. The viewing apparatus further comprises a relay lens group which conditions the light into a quasi-collimated state before it enters the optical elements allowing a more compact device to be produced. The viewing apparatus may additionally include a zoom lens mechanism to enable the viewed image to be enlarged.
