摘要：
A device configured for low-energy ultrasonic 2D Fourier transform analysis, comprising: (i) a first layer comprising an array of piezoelectric pixels; (ii) a second layer comprising an array of piezoelectric pixels; (iii) a third layer, positioned between the first and second layers, comprising a bulk ultrasonic transmission medium; wherein the second layer of array of piezoelectric pixels is in the Fourier plane of an input signal of the first layer array of piezoelectric pixels.
