Abstract
Three basic approaches to acoustic imaging are described: focused imaging, which uses acoustic lenses or reflectors to form an image; holographic imaging, which reconstructs images from detected wavefronts; and high-resolution beamforming imaging, which maps the object plane into the image plane by scanning. For each system type, possible hardware implementations are described with specific examples of existing systems. In addition, problems associated with each technique are discussed.
