The receiving process of the transducer also obeys the geometric focusing delay law, and is a reciprocal process with the transmitting state of the transducer. In detection, an acoustic beam propagates in a medium according to a certain rule, and when acoustic impedance of a defect in the medium changes, a reflected signal with certain sound intensity is generated. The paths of the point to each array element in the transducer array are different, resulting in a certain difference in the time of arrival of the reflected signal generated at the point to each array element. Each array element carries out delay summation on echo signals according to a set delay delta t, so that echo signals from defects are in phase, the purpose of enhancement is achieved, and receiving focusing is realized.

The front length L 1 of the incident point of the wedge 1 refers to the distance from the incident point of the wedge 1 to the front edge of the probe 2 under the natural angle, and it should be noted that in phased array detection, the incident point of the probe 2 will shift under different focusing rules, so that when the front length of the wedge 1 is calibrated, the focusing rule is not set, and the calibration is performed under the natural refraction angle. The length L 2 of the rear edge of the incidence point of the wedge 1 refers to the distance from the incidence point of the wedge 1 to the rear edge of the probe 2 under the natural angle. L 3 in the figure is the width of the wedge, and refers to the length of the bottom surface of the wedge 1 along the direction of the driven shaft. The intra-wedge acoustic path L 4 of the wedge 1 refers to the length of a connection line between the array center of the array element of the probe 2 and the incident point at the natural incident angle, and the connection line L 4 is perpendicular to the array element of the probe 2.
