1. A system for removing a coating from an underlying layer, the system comprising:
a housing defining an opening, wherein the opening is configured to be adjacent to the coating;
a light source configured to emit electromagnetic radiation directed toward the opening, wherein the light source is coupled to the housing;
an ultrasonic emitter configured to emit ultrasonic waves directed toward the opening, wherein the ultrasonic emitter is coupled to the housing;
a coating removal mechanism configured to remove the coating from the underlying layer, wherein the coating removal mechanism is coupled to the housing; and
a sensor configured to determine a property associated with the coating, wherein a system operation parameter is determined based on the property;
wherein the ultrasonic emitter is operable between:
a contact mode wherein the ultrasonic emitter directly contacts the coating; and
a noncontact mode wherein the ultrasonic emitter is a distance above the coating.
