Abstract
Abstract An apparatus and method for the remote visualization and inspection of an internal storage space, such as a ship's hold. The apparatus includes a mounting stand to which is rotationally mounted a support shaft, the support shaft having a camera and a light source secured thereto. The camera and light source rotate with the support shaft, and are pivotally movable relative to the support shaft. A drive shaft extends through the support shaft and is operable to simultaneously pivot the light source and camera. A light adjustment drive shaft is mounted to the hollow support shaft and allows the operator to pivot the light source independently of the camera to permit a wider field of view than would otherwise be available. The apparatus is inserted, via an access opening, into a storage space and thereafter operated to allow an inspector, located outside of the storage space, to visually inspect the surfaces surrounding and defining the storage space.
