Laser-based ultrasonics (LBU) is now becoming a more mature technology, making the transition from research laboratory equipment to industrial on-line measurement system possible. The non-contact and remote capability of LBU is an undeniable advantage for high-speed inspection. A major challenge for LBU receivers is to overcome the random phase and… CONTINUE READING
