A New method for non-destructive testing (NDT) of surface-breaking tight cracks based on laser-induced nce acoustic waves (SAW) is proposed. A Q-switched Nd:YAG laser is used to generate SAW through Live interaction between material and the laser pulses. The SAW is probed by an optical interferometer as a o displacement of the surface. A state-of-the-art technique in laser-ultrasonic NDT is reviewed: that is the < depth measurement by using fr equency analysis of SAW transmitted through cracks. The techni...

A new method for non-destructive testing（NDT）of surface-breaking tight cracks based on laser-induced surface acoustic waves（SAW）is proposed. A Q-switched Nd:YAG laser is used to generate SAW through ablative interaction between material and laser pulse. The SAW is probed by an optical interferometer as a micro displacement of the surface. A state-of-the-art technique in laser- ultrasonic NDT is developed: that is the crack depth measurement by using frequency analysis of laser-induced SAW transmitted throug...
