METHOD AND APPARATUS FOR VIBROACOUSTIC MODULATION CRACK DETECTION AND CHARACTERIZATION OF CONDUITS

摘要

A crack detecting system operable to detect cracks along a conduit or structure includes a tool movable along a conduit or structure and having at least one sensing device for sensing cracks in a wall of the conduit or structure. A processor is operable to process an output of the at least one sensing device. Responsive to processing of the output by the processor, the processor is operable to determine the presence of cracks at the wall of the conduit or structure. The at least one sensing device includes or provides a vibroacoustic modulation technique.
