Abstract
Advanced nondestructive testing techniques use a laser to generate ult rasonic waves at the surface of a test material. An air-coupled transd ucer receives the ultrasound that is the convolution of the signal lea ving the test material and the distortion function, Blind deconvolutio n methods are applied to estimate the signal leaving the material.
