摘要
超声成像检测(UID)技术具有检测结果直观等优势,是无损检测领域未来的主要发展方向之一。相比传统超声检测方式,激光超声因具有非接触式的特点成为重要检测手段。时间反转成像法可实现时间和空间的自适应聚焦,在非均匀介质中对目标的定位和检测具有广阔前景。介绍了以时间反转法为主的几种典型超声成像方法,对比分析不同成像算法的结果,介绍了超声成像领域常用的仿真软件。以激光超声为切入点对比常规超声,给出了现代超声检测技术概况和国内外先进的工业超声成像检测仪器设备概况,并对未来的成像检测技术进行了简要分析和展望。
Ultrasonic imaging detection(UID)technology has the advantages of intuitive test results,and is one of the main development directions in the field of nondestructive testing in the future.Compared to traditional ultrasonic testing methods,laser ultrasonic detection has gained popularity due to its non-contact characteristics.The time reversal imaging method has a potential application in locating and detecting targets in inhomogeneous media due to its ability of acoustic beam self-focusing in time and space domains.This study primarily reviews the time reversal method and other conventional ultrasonic imaging methods.The results of different imaging algorithms used in the data post-processing are compared and analyzed.Moreover,the professional simulation softwares available for use in the ultrasonic imaging field are briefly summarized.Starting from laser ultrasound and compared to conventional ultrasound,the general situation of the modern ultrasonic testing technology and the advanced industrial ultrasonic imaging testing instruments and equipment at home and abroad are discussed.Further,the future imaging testing technology is briefly analyzed.
