Abstract
An acousto-optic imaging system may include at least one transducer that transmits an ultrasound signal having a fundamental frequency f. The acousto-optic imaging system includes at least one optical sensor that may produce one or more optical responses upon receiving harmonic-related ultrasound echoes corresponding to the transmitted ultrasound signal. For example, the one or more optical sensors may have a bandwidth ranging from at least f/M to Nf, where M and N are integers greater than 1.
