The Present Development Situation of Laser Ultrasonic Nondestructive Testing Signal Processing System

Abstract:

Currently, laser ultrasonic nondestructive testing is the best application prospect of nondestructive testing methods. This paper expounds the mechanism and the qualitative analysis of the common defects of the laser ultrasonic inspection and introduces the application of matching pursuit algorithm guided wave testing technology in signal processing. This paper focuses on the laser ultrasonic detection system and analysis of the detected data using the finite element method.
