Abstract
Certain examples provide a transparent ultrasonic transducer including a transparent substrate and a transparent optical resonator positioned on the transparent substrate. The transparent optical resonator is to facilitate excitation of a biological sample and to receive acoustic emission from the biological sample triggered by the excitation, for example.Certain examples provide a ring resonator ultrasonic detector including a microscope cover slide. The microscope cover sheet includes a substrate and a ring optical resonator positioned on the substrate. The example ring optical resonator is to facilitate illumination of a biological sample and to receive acoustic emission from the biological sample in response to the illumination.
