人工缺陷对激光超声响应的初步研究
EFFECT OF SIMULATED DEFECTS ON LASER ULTRASOUND:AN EXPERIMENTAL STUDY
【摘要】 用 Q 开关 YAG 激光器在金属材料中激励超声脉冲,用压电换能器接收超声脉冲,并对某些人工缺陷对超声脉冲的响应进行了实验研究。
【Abstract】 The effect of simulated defects on ultrasonic pulses was studied experimentally bygenerating ultrasonic pulses in metal with a Q-switched YAG laser and receiving them with a piezoelec-tric transducer.
