Ultrasonic test system using a fiber optic detector, ultrasound test method and aircraft structural object

摘要

An ultrasound test system (1) comprising: an ultrasound propagation body (4) configured to modify at least one direction of travel of at least one ultrasound wave that propagates in a test target (O) and is introduces into the ultrasound propagation body (4); and a fiber optic detector (5) attached to the ultrasound propagation body (4) so that at least one ultrasound wave propagates inside the ultrasound propagation body (4) to the fiber optic detector (5), the fiber optic detector (5) being configured to detect the at least one ultrasound wave, the at least one direction of movement of which has been modified by the ultrasound propagating body (4), characterized in that at least one ultrasound wave it is at least one Lamb wave; and the ultrasonic propagating body (4) is a thin plate (7) or thin plates (7A, 7B) configured to modify at least one direction of displacement of the at least one Lamb wave.
