Abstract: A scanning fixture for use in moving a tool across a surface of an object is arranged to be attached to the object and comprises: a carriage arranged to have the tool connected thereto; and a frame arranged to be mounted on the object and to have the carriage mounted thereon. The frame comprises: a first mount arranged to be mounted on the object; a second mount arranged to be mounted on the object; a carriage support arranged to extend between the first and second mounts, across a surface of the object, and to have the carriage moveably connected thereto. The carriage support is a modular carriage support, comprising a plurality of modules rotatably mounted on an elongate member. The plurality of modules together form a path along which the carriage can move. The tool may be a probe for use in inspecting the object. The fixture may comprise one or more encoders arranged to generate position data for the carriage.
