Abstract: Using a photoacoustic effect, a non-destructive and non-contact sensor has been studied. This paper reports on the optimization of defect detection system with a semiconductor laser to get larger photoacoustic signal. Photoacoustic signal increases with increasing laser power. Photoacoustic signal modulated by pulse wave is greater than that by sinusoidal wave. This system has a higher resolution than the other ultrasonic test system. It is confirmed that the defect completely shut in sample can be detected.
