Abstract
An apparatus includes a glass element, a fluid, an illumination source, and an ultrasound emitter. The glass element is immersed in the fluid. The illumination source emits light. The ultrasound emitter is configured to direct an ultrasonic signal through the fluid to the glass element. The glass element is configured to reflect the ultrasonic signal along a substantially similar path as an optical path that the light propagates along.
