Ultrasonic sensors can emit ultrasonic waves and receive their reflected waves. By analyzing the characteristics of the reflected waves, such as time, amplitude, and waveform, it is possible to determine whether there are defects inside the object, as well as the location, size, and shape of the defects. For example, when inspecting cables, it is possible to see if there are any small cracks in the cable.
