Abstract : The patent relates to a ship's bottom inspection apparatus which includes a generally U-shaped framework which is adapted to be submerged for receiving the width of a ship therebetween. A series of cameras are mounted in a spaced relationship along the framework to view vertically upward. A series of lights are mounted in a spaced relationship along the framework at an acute angle to vertical and directed generally toward the viewing area of the cameras so that backscattering is minimized while ship bottom discontinuities are made evident by shadow effects. In this manner multiple photographs can be taken of the ship's bottom to display and possible structural defects.
