Abstract

An ultrasonic microscope is provided wherein a sample placed in a medium is irradiated with a focused ultrasonic wave from a focusing ultrasonic transmitting element and the focused ultrasonic wave is detected by a focusing ultrasonic receiving element. The sample (or the focusing transmitting element and the focusing ultrasonic receiving element) is moved within the X-Y plane, and either the focusing transmitting element or the focusing ultrasonic receiving element is vibrated toward the sample along the beam axis.
