Abstract: This paper analyzes the ultrasonic modulation of coherent light in Raman–Nath acousto-optic diffraction. We find that the frequency shifts of the diffracted light cause the periodic variation of the ultrasound-modulated light intensity with time. Additionally,… read more here.

Abstract: The laser ultrasonic technique is gaining popularity for nondestructive evaluation (NDE) applications because it is a noncontact and couplant-free method and can inspect a target from a remote distance. For the conventional laser ultrasonic techniques,… read more here.
