Classification: CPC G  H | IPC G  H

Claim 19:
20. A device configured for low-energy ultrasonic 2D Fourier transform analysis, comprising:
a bulk ultrasonic transmission medium;
a first array of piezoelectric pixels, comprising a first plurality of pixels, disposed on a first side of the bulk ultrasonic transmission medium;
a second array of piezoelectric pixels, comprising a second plurality of pixels, disposed on the first side of the bulk ultrasonic transmission medium; and
a reflector disposed at a second side of the bulk ultrasonic transmission medium opposite the first side,
wherein the first array of piezoelectric pixels is configured to output an ultrasonic wave toward the reflector responsive to an input signal comprising an input phase and an input magnitude, and
wherein the second array of piezoelectric pixels corresponds to a Fourier plane for the ultrasonic wave output by the first array of piezoelectric pixels.
