摘要:
According to one embodiment, an ultrasonic test system includes an ultrasonic transmission part including at least one ultrasonic transducer, an ultrasonic detection part including at least one sensor and damage detection part consisting of circuitry. The ultrasonic transducer transmits a first ultrasonic wave and a second ultrasonic wave toward a test region. The first ultrasonic wave has a relatively low frequency. The second ultrasonic wave has a frequency higher than the frequency of the first ultrasonic wave. The sensor detects a reflected wave of the first ultrasonic wave and the second ultrasonic wave which has passed through the test region. The reflected wave is from the test region. The damage detection circuitry is configured to detect a damage in the test region, based on the reflected wave of the first ultrasonic wave and the second ultrasonic wave which has passed through the test region.
