Description

High resolution beam-deflection techniques have been applied to the ultrasonic inspection of materials. The technique is similar to air-coupled detection, with the airborne wave detected through beam deflection instead of with an electro-acoustic transducer. It is a non-contact, laser based, detection technique that does not require reflection of the detection laser beam from the surface. It is thus independent of the surface optical properties of the material under test.
