Abstract
Advanced nondestructive testing techniques use a laser to generate ultrasonic waves at the surface of a test material. An air-coupled transducer receives the ultrasound that is the convolution of the signal leaving the test material and the distortion function. Blind deconvolution methods are applied to estimate the signal leaving the material
