Abstract

An echo sounding apparatus which includes an ultrasonic transmitter-receiver probe 3 generating a horizontal ultrasonic beam and a mirror 4 inclined at 45.degree. with respect to the said beam and driven by a torque motor 5 for oscillatory conical motion about an axis which coincides with the said beam. A housing 1 containing a coupling liquid transmits the investigation ultrasonic beam reflected on the mirror through a transparent membrane 2. An auxiliary ultrasonic reflector, which follows the angular displacement of the mirror, cooperates with an auxiliary transducer, operated in synchronization with the said probe, for providing a signal indicative of the angular position of the mirror. The torque motor is controlled from the said signal so that the mirror is oscillated in accordance with a pre-determined scanning law and a circuit controls the displacement of the beam of a cathode ray tube so as to provide a type B display where the scanning of the screen of this tube continuously corresponds to the displacement of the ultrasonic beam.
