ABSTRACT:
A two-dimensional bulk acoustic wave correlator-convolver having an acoustic mirror positioned two focal lengths from an integrated circuit-acoustic transducer array. The image, rather than the Fourier transform, of the input spatial distribution is returned to the transducer array by the mirror.
