Patent attributes
A method and survey system for inspecting hulls of ships has a base portion and side portions defining an inspection channel in water. Sonar is mounted on the side portions transmitting acoustic signals onto a hull as a ship passes through the inspection channel, receiving reflected acoustic signal portions of the transmitted acoustic signals, and converting the reflected acoustic signal portions into electromagnetic acousto-signals corresponding to the hull and objects on the hull. An electro-optic scanning array is mounted on the base member transmitting optical signals onto the hull as the ship passes through the inspection channel, receiving reflected optical signal portions of the transmitted optical signals, and converting the reflected optical signal portions into electromagnetic opto-signals corresponding to the hull and objects on the hull. A control module receiving the corresponding electromagnetic acousto-signals and opto-signals transmits these signals as amplified RF signals.
