Abstract
A high frequency ultrasound analog beamformer comprises a linear array of surface acoustic wave (SAW) devices formed on a single crystal piezoelectric substrate, such as a PMN-PT single crystal piezoelectric substrate. Each SAW device comprises ultrasound input and output electrode structures separated by a variable delay structure. The beamformer further comprises a delay controller operably connected to each variable delay structure to control the delay of each SAW device to dynamically focus signals received at each input electrode.
