| Research Abstract |
A generation laser scanning method for onsite visualization of ultrasonic propagations was developed. We applied this method to nondestructive inspection of defects of prototype specimens of industrial plant pipes and a rocket combustion chamber. From the measured dynamic images, we could observe the defect echoes as they scatter radially on the surface of the specimen. These results indicate that this method can be effective for nondestructive inspection of structures and materials.
