Superresolution in Ultrasonic Imaging
Since it has been demonstrated that superresolving acousto-optical systems can be realized the question of their applicability to the imaging of other than point sources arises. This paper reviews the experimental and theoretical evidence for the possibility of superresolution and explains why it is of particular interest to ultrasonic imaging. The problems relating to the limits imposed by information theory to the imaging of distributed objects is examined and a method of obtaining the necessary spatial bandwidths is discussed.
