Abstract: There is provided a modular scanner and probe holding apparatus for inspection, which consists of an assembly of a plurality of connective links rigidly connected. The connective links are added or removed from the assembly to size the assembly so the assembly extends more than half way around a circumference of a tubular body to be inspected. At least one tail link is connected to an end of the assembly. The tail link is biased by a spring to apply a force against the tubular body to hold the assembly in place. A probe holder link is provided that connects to the connective links and has a probe holder for holding a probe.

Abstract: A modular scanner assembly includes a probe holder support constructed from interconnected reconfigurable members. At least one of the interconnected reconfigurable members has a probe holder. The probe holder support has wheels attached to at least one interconnected reconfigurable member for moving the probe holder support across a surface to be scanned. At least one of the wheels is connected to a position encoder.
