摘要： A method of inspecting a plate-like structure (2) by means of ultrasound for detecting anomalies (3) in the structure, comprising: positioning at least three ultrasonic transmitting/receiving probes (4) in Hertzian contact with a surface of the structure (2) and in a polygonal configuration such that an inspection area (6) of the structure is defined by the configuration; successively drive one probe (4) at the time as an ultrasound transmitting probe generating an ultrasound wave propagating into a plane of the structure in the inspection area (6), while at least one of the other probes (4) is arranged to be used as an ultrasound receiver detecting a resulting wave provided by the ultrasound wave propagating through the inspection area (6); acquiring signals corresponding to waves detected by the second probes (4) and comparing the acquired signals with reference signals for a corresponding inspection area of a reference structure without anomalies.

摘要： A method, a computer program and a system for ultrasonic inspecting of objects is provided. The method comprises positioning (103) a measuring device (11) comprising a plurality of transducers (12)on the inspected object(20) and performing a number of test signal acquisitions (103). Each acquisition includes using one transducer to induce an ultrasonic signal into the test object, and using at least one other transducer to receive an ultrasonic test signal. The inspecting further comprises determining (105, 205) the influence of contact surface variations between each test signal and a reference signal; compensating (106, 206) the full test signal for the contact surface variations; and determining (109) a residual signal. The system comprises a computing device (30), and a measuring system (13) communicatively connected to the computing device (30). The measuring system (13) includes an ultrasound unit (19) and a measuring device (11) provided with a plurality of transducers (12).The computing device (30) comprises a calibrator (303) to determine(105, 205) the influence of contact surface variations, and compensate(106, 206) the test signal. The computing device (30) comprises a residual calculator (304) to determine(109) the residual signal.
