More Information
Summary:Disclosed herein is a laser ultrasonic testing (UT) apparatus for inspecting a surface of an object. The laser UT apparatus comprises an excitation laser, which is selectively operable to generate an excitation laser beam. The laser UT apparatus also comprises a first acousto-optic deflector (AOD) and a second AOD. The laser UT apparatus additionally comprises a detection laser, which is selectively operable to generate a detection laser beam. The laser UT apparatus further comprises a third AOD and a fourth AOD.
