Abstract:
(EN) The ultrasonic inspection system according to an embodiment of the present invention is provided with a first inspection unit, a second inspection unit, and a signal processing system. The first inspection unit acquires a detection signal of a first ultrasonic wave in a first inspection section of a structure by using a first ultrasonic transducer and a first ultrasonic sensor. The second inspection unit acquires a detection signal of a second ultrasonic wave in a second inspection section of the structure by using a second ultrasonic transducer and a second ultrasonic sensor. The signal processing system obtains an index value indicative of inspection information about at least one of the first inspection section and the second inspection section on the basis of the detection signal of the first ultrasonic wave and the detection signal of the second ultrasonic wave.
(FR) Le système d'inspection par ultrasons selon un mode de réalisation de la présente invention comporte une première unité d'inspection, une seconde unité d'inspection et un système de traitement de signal. La première unité d'inspection acquiert un signal de détection d'une première onde ultrasonore dans une première section d'inspection d'une structure à l'aide d'un premier transducteur ultrasonique et d'un premier capteur ultrasonique. La seconde unité d'inspection acquiert un signal de détection d'une seconde onde ultrasonore dans une seconde section d'inspection de la structure à l'aide d'un second transducteur ultrasonique et d'un second capteur ultrasonique. Le système de traitement de signal obtient une valeur d'indice indicative d'informations d'inspection concernant au moins l'une de la première section d'inspection et de la seconde section d'inspection sur la base du signal de détection de la première onde ultrasonore et du signal de détection de la seconde onde ultrasonore.
(JA) 実施形態に係る超音波検査システムは、第1の検査ユニット、第2の検査ユニット及び信号処理系を備える。第1の検査ユニットは、第1の超音波振動子及び第1の超音波センサを用いて構造体の第1の検査区域における第1の超音波の検出信号を取得する。第2の検査ユニットは、第2の超音波振動子及び第2の超音波センサを用いて構造体の第2の検査区域における第2の超音波の検出信号を取得する。信号処理系は、前記第1の超音波の検出信号及び前記第2の超音波の検出信号に基づいて、前記第1の検査区域及び前記第2の検査区域の少なくとも一方の検査情報を表す指標値を求める。
