ABSTRACT:
An ultrasonic microscope includes a sample rod for supporting a sample and an acoustic lens positioned to face the sample. The lens is moved in two directions in a plane perpendicular to each other to scan the sample. During the scanning operation, the lens is also moved in a vertical direction so that the distance between the sample and acoustic lens is changed, by a piezoelectric actuator for supporting the lens.
