Abstract
In one embodiment, a pipe inspecting apparatus includes a selection module configured to select first and second ultrasonic optical probes from a plurality of ultrasonic optical probes attached to a pipe. The apparatus further includes a power supplying module configured to supply power to an ultrasonic transducer of the first ultrasonic optical probe to input an ultrasonic wave from the ultrasonic transducer to the pipe and to supply the ultrasonic wave via the pipe to an optical fiber sensor of the second ultrasonic optical probe. The apparatus further includes a light detection module configured to detect laser light transmitted through the optical fiber sensor of the second ultrasonic optical probe.
