Abstract

1. An ultrasonic transducer having a supporting body (2), a transmitting layer (4) of a material with a relatively high dielectric constant and high acoustic impedance and a first lambda/4 coupling layer (8) that faces the transmitting layer (4), and a second lambda/4 coupling layer that faces a load, characterised in that the second lambda/4 coupling layer also serves as a receiving layer (6) and that the first lambda/4 coupling layer (8) also serves as backing for the receiving layer (6).
