Abstract
A transducer for generating acoustic waves more particularly for generating compression waves, comprising an array of transmitter elements and an array of receiver elements, at least one wedge for the array of transmitter elements and the array of receiver elements and preferably an acoustical barrier separating the array of transmitter elements and the array of receiver elements. The pitch of the transmitter array varies along the length of the transmitter array.
