Abstract
An acoustic imaging system coupled to an acoustic medium to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers formed at least in part from a thin-film piezoelectric material, such as PVDF. The array is coupled to the acoustic medium opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage on or more beamforming scan operations to drive the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.
