Abstract
A method and apparatus for testing a bond interface is provided. The method comprises directing laser energy at a first surface of a first material connected to a second material by an adhesive at a bond interface. The first surface is opposite the bond interface. A first acoustic impedance of the first material is greater than a second acoustic impedance of the second material. The method also determines whether an inconsistency is present in the bond interface after directing the laser energy.
Claims21
A method comprising:
- directing laser energy at a first surface of a first material connected to a second material by an adhesive at a bond interface, wherein the first surface is opposite the bond interface, wherein a first acoustic impedance of the first material is greater than a second acoustic impedance of the second material;
- and
- determining whether an inconsistency is present in the bond interface after directing the laser energy.
A method comprising:
- transmitting an initial wave into a first surface of a first material connected to a second material by an adhesive at a bond interface, wherein the first surface is opposite the bond interface, and wherein a first acoustic impedance of the first material is greater than a second acoustic impedance of the second material;
- and
- determining whether an inconsistency is present in the bond interface after transmitting the initial wave.
