Abstract
This transducer comprises means (16 to 24, 56 to 60) for determining the respective positions of ultrasound emitting elements (6) with respect to an object to be inspected (8) during displacement of the transducer. Means (62) generate pulses exciting emitting elements, and create delay laws starting from determined positions enabling emitting elements to generate a focused ultrasonic beam (F), and apply these laws to the excitation pulses. Ultrasound receiving elements provide signals used to form images related to the object. Application to medicine and nondestructive testing.
