Abstract

An acoustic transducer for generating and/or receiving a spatially structured acoustic field includes a total aperture which generates and/or receives the acoustic field. The total aperture includes a plurality of sub-apertures. Each of the sub-apertures is arranged to receive and/or generate ultrasound having a specific frequency spectrum. The specific frequency spectra of at least two of the sub-apertures differ. All sub-apertures of the total aperture are connected to a same electronic drive channel.
