A Probe of multi-beam of light interference for Laser-Ultrasonic Testing

    Abstract
  • The paper presents a probe design of sensitive to surface velocity of the target for laser-ultrasonic testing.Based on the fundamental works of Doppler effect for laser generated by ultrasonic vibration of the target surface and multi-beam of light interference.The probe advantage are adjustment convenience,work stabilization and practicability better.
