Abstract
An ultrasonic detecting apparatus includes a transmitting element for emitting an ultrasonic wave toward a surface to be probed inside a sample from a surface of the sample at a predetermined angle. The ultrasonic detecting apparatus also includes a receiving element for receiving the ultrasonic wave reflected from the surface of the sample. The transmitting element and the receiving element are separated from each other on a single pedestal and are movable on the surface of the sample in a direction perpendicular to the surface to be probed. A distance between the transmitting element and the receiving element is arbitrarily changeable.
