1. A method for dynamically acquiring data representing a metal part to be tested, said method comprising:
a step of acquiring data concerning the part to be tested, with said data being obtained by a multi-element sensor, said sensor comprising transmitting elements and receiving elements, the transmitting elements being configured to transmit a respective ultrasonic shot toward the part to be tested so that said ultrasonic shot propagates through the part to be tested, with the receiving elements being configured to receive waves reflected by the part to be tested resulting from the ultrasonic shot, said acquisition step comprising:
transmitting an ultrasonic transmission shot from one of said transmitting elements; and
said receiving elements receiving, during a listening duration, ultrasonic waves, with said received ultrasonic waves comprising one of said waves reflected by the part to be tested resulting from the transmitted ultrasonic shot;
the method further comprising a step of generating data representing the part to be tested as a function of the waves received by the receiving elements;
wherein said method further comprises, during the data acquisition step, a step of moving one from among the part to be tested and the sensor so as to generate a relative movement between the sensor and the part to be tested; and
wherein said method further comprises a step of generating corrected data representing the part to be tested, with said step of generating corrected data comprising:
computing a corrective movement as a function of the relative movement between the sensor and the part to be tested, of a reference position and of a duration relative to a reference instant, with the reference position corresponding to a relative position between the sensor and the part to be tested at the reference instant, with said reference instant having occurred during the data acquisition step, said corrective movement corresponding to a relative movement between the sensor and the part to be tested up to the reference position from a relative position corresponding to the relative position between the sensor and the part to be tested at an instant of said duration relative to the reference instant; and
applying a correction to the data representing the part to be tested as a function of the computed corrective movement so as to generate said corrected data by simulating a relative movement between the sensor and the part to be tested from a relative position between the sensor and the part to be tested at the instant of said duration up to the reference position.
