Abstract
The invention relates to a periscope installation sighting head, particuly for a submarine, located at the upper end of a periscope mast and including at least one optical sighting unit off-set laterally with respect to the axis of the mast. To stabilize, in azimuth and in elevation, the image provided by the sighting unit when the mast is animated by a swinging movement, the sighting unit is positioned on a mobile support with two gyrostabilized axles and a trajectory correction device as a parallel-sided plate is interposed in the path of the signals delivered by said unit and is slaved to the azimuth of the unit so that the signals are transmitted to the mast substantially along the optical axis of the latter.
