An apparatus and method for non-destructive examination of an interface within a body between two separate elements of the body wherein an acoustic microscope (124) has an ultrasonic transmitter (114) for directing ultrasonic waves at an angle to a body (1) and an interface (122) within the body between an outer part (3) and an inner part (2), an acoustic receiver (116) in spaced relationship to the transmitter (114) for receiving acoustic leaky waves from the interface (122), and a supporting device for supporting the transmitter and receiver for simultaneous scanning movement relative to the body at the same scanning speed. The body to be examined may be supported immersed in a liquid such as water (120) in a tank (121) so that the ultrasonic waves from the transmitter are directed at a predetermined angle depending on the materials of the separate elements and-pass through the liquid and the outer part before impinging on the interface in the body to be examined.

An apparatus for non-destructive examination of at least one interface within a body between at least two separate elements of the body, comprising: an acoustic microscope comprising an ultrasonic transmitter for transmitting ultrasonic waves toward said body to be examined to produce an interface wave along said at least one interface, and an ultrasonic receiver for receiving acoustic leaking energy from said interface wave at said at least one interface; means for supporting said body; and means for supporting said ultrasonic transmitter and receiver in relative spaced relationship for simultaneous scanning movement with respect to said body at the same scanning speed so that said transmitter produces transmitted ultrasonic waves penetrating one of said elements of said body at a predetermined angle and propagating an interface wave along said at least one interface which radiates said acoustic leaking energy detectable by said receiver.
