Description:  1. An optical or electro-optical instrument designed to displace the line of sight in a vertical plane when eye level vision may not be practical or possible, as in intrenchments, tanks, submarines, and the like. The raised line of vision is obtained by the use of mirrors or prisms and/or a camera array with the item, permitting a line of vision on a plane other than that of the observer. It may have a single or double optical system(s). It may include a laser range finder, one or more antennas, and the like.
