Line Focus Acoustic Lens with Wedge Transducer Source

  • Chapter
Acoustical Imaging

Part of the book series: Acoustical Imaging ((ACIM,volume 17))

Abstract

Results are reported for a new concept in line focus acoustic microscopy. We use a wedge shaped lithium niobate transducer as the source for a standard cylindrical lens. The resonant frequency varies with position down the axis so that the frequency can be used to spa tiallv vary the focal point position along the focal line.
