Abstract

The work presented in this paper focuses on a novel method that is laser-induced ultrasonic (LIU) imaging detection based on interferometric synthetic aperture focusing technology (InSAFT). The approach adopted is combing interferometry technology with synthetic aperture focusing technology (SAFT). A set of numerical simulations to test the validity of LIUInSAFT imaging detection were performed by the finite element method (FEM). The results of the simulation indicate that the height of target determined by LIU-InSAFT agrees well with that of setting value in the mode of simulation. All the preliminary results throw light on the nature of LIU-InSAFT applied to height detection or inner roughness of inner surface in materials.
