Abstract
A panoramic view of the world surrounding a stationary mast of a submarine is provided by a plurality of small windows disposed circumferentially around the mast and a corresponding plurality of lenses for imaging the fields of view thereof onto coherent fiber optic image bundles. The fields of view of the lenses overlap to provide a complete panoramic view. The exit ends of the image guides are arranged to form a polygonal opening so that a replica of the panoramic view is provided within the opening. A mirror or prism rotating within the opening scans the view replica and directs the scanned image to a stationary television camera. A derotating prism in the path of the directed scanned image rotates at one-half the angular displacement of the image director to compensate for rotation imparted to the scanned image by the image director.
