    Abstract: A laser ultrasound system may be utilized to test material quality. The laser ultrasound system may generate a laser for application to a material and measure signal generated by the application of the laser to the material. The measured signals may be altered based on correction factors and the quality of the material may be determined based on the altered signals.
