Abstract
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 or the second type is a tunable optical resonator and selectively configured to operate in different quality factor modes, 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.
