摘要：
A system for nondestructive evaluation of a test object includes a platform, an electromagnetic acoustic transducer (EMAT) to create acoustic vibrations that travel along the test object; an infrared detector positioned to record thermal images of a plurality of test areas on the test object to detect flaws in the test object as the platform and the test object move relative to each other; and a control connected to actuate the EMAT and the infrared detector, synchronize the creation of vibrations with the recording of thermal images, receive a signal from the infrared detector indicative of the thermal image of the surface of the test object, and record locations of the flaws appearing on the thermal images of the test areas, all as the platform and the test object move relative to each other.
