Abstract
A multitransducer ultrasonic probe having transducers of different sizes for the nondestructive testing of mechanical parts. The probe has at least one line of M transmitter and/or receiver ultrasonic transducers, a control unit for the activation of at least one group of m juxtaposed transducers, selected from the M transducers and for the displacement of the activated portion of the probe after each activation. The M transducers all have different sizes and are arranged in monotonic manner in accordance with their sizes, the sizes being determined so as to scan an object to be inspected with a redundancy rate which is independent of the depth of the locus to be inspected.
