Claim Text:
1. An apparatus comprising: a wave generator positioned away from an object, wherein the wave generator emits an ultrasonic wave in a direction towards a location on the object such that the ultrasonic wave encounters a portion of the object; a detection system positioned at a same side of the object as the wave generator, wherein the detection system detects a feature response of a feature within the portion of the object to the ultrasonic wave encountering the portion of the object; and wherein: the feature response is a portion of a response that is different from a rest of the response and corresponds to an amplified vibration of the feature relative to a rest of the portion of the object in response to the ultrasonic wave encountering the portion of the object; and the detection system is configured to detect the amplified vibration of the feature using at least one of a thermographic imaging system configured to detect heat generated by the amplified vibration, an infrared thermographic imaging system configured to detect infrared radiation generated by the amplified vibration, an imaging system configured to detect and magnify surface motion produced by the amplified vibration, an optical interferometry system, an electronic speckle pattern interferometry system, or a shearography system.
