Conventional ultrasonic testing has been considered to be difficult to:
・ Detect objects with acoustic anisotropy
・ Detect and size tilted scratches
・ Detect fine scratches using a low-frequency probe
An ultrasonic inspection technology that applies the Full Matrix Capture (FMC)/Total Focusing Method (TFM) method, also known as the aperture synthesis method, makes it possible to measure these with high resolution and accuracy.
