【Abstract】 Described are the techniques of ultrasonic signal analysis and real-time defect imaging of NY-101 ultrasonic imaging unit. The unit can be used not only for digital detection but also for real~time C+A scan and image post-processing. The situ testing results show that the precision of defect location and sizing can be im-proved.更多还原
