In panel (a), a schematic of the AO sensor before insonification by an ultrasound field is shown alongside an image of the AO sensor, when the LC molecules are aligned along the optical axis. In panel (b), a schematic of the AO sensor after insonification by an ultrasound field is shown alongside an image of the AO sensor, when the LC molecules have been perturbed by an ultrasound field.
(a) AO sensor without ultrasound (full dark field image)
(b) AO sensor stimulated with ultrasound (area shown as bright spot)
