A system and method for inspecting a structure having a coating on at least one surface is provided. The system includes at least one ultrasonic sensor positioned proximate to the structure. Each sensor is capable of transmitting a shear wave toward the structure and receiving return signals in response thereto, wherein the shear wave comprises at least one of a reference beam and an interrogating beam. The system further includes a data acquisition system in communication with the sensor for generating information indicative of the coating based on at least one return signal associated with the reference beam. |
