    摘要: A method of imaging may include receiving a first signal from one or more array elements of a first type in a mixed transducer array, receiving a second signal from one or more array elements of a second type in the mixed transducer array where at least one of the first type and the second type is an optical sensor, generating a first image from the first signal and a second image from the second signal, and combining the first image and the second image to generate a compound image.

    摘要: A method of acousto-optic imaging may include receiving a first signal from a first sub-aperture of a sensor array. The first sub-aperture may comprise one or more array elements of a first type. The method may further include receiving a second signal from a second sub-aperture of the sensor array. The second sub-aperture may comprise one or more array elements of a second type different from the first type. In some variations, the first type of array element may be an acoustic transducer (e.g., piezoelectric transducer) and/or the second type of array element may be an optical sensor (e.g., optical resonator such as a whispering gallery mode (WGM) resonator). The method may further include combining the first signal and the second signal to form a synthesized aperture for the sensor array.
