Self-focusing transducers
text:
Acoustic waves emitted by ultrasonics transducer crystals exhibit a property known as self-focusing. Note that this is distinct from the electronically controlled focusing employed in diagnostic ultrasound devices which employ arrays of transducers. The self-focusing effect exists even for a single crystal. Self-focusing refers to the narrowing of the ultrasonic beam in the near-field. The effect occurs because,
if the ultrasound wave generated by the crystal is coherent,
