摘要:
近年来,超声成像检测技术取得了快速发展,已成为无损检测领域的研究热点。本文重点分析了声波时间反转成像、超声相控阵成像、合成孔径成像、全聚焦成像、频散导波成像和超声多波成像这6种超声成像检测方法的发展历程、研究现状及进展。分析表明:声波时间反转成像是一种自适应聚焦成像方法,在原理上不适用于非线性和耗散介质,需要适当改进才能应用。超声相控阵成像、合成孔径成像和全聚焦成像都是基于超声阵列的相位控制方法,能实现声束可调,随着电子硬件和软件技术的发展,超声阵列成像将向三维实时成像方向发展。分析了频散导波和多波聚焦的成像特点,讨论了通过控制换能器各阵元激励信号波形来实现频散导波和多波聚焦成像的多种方法。总结了超声成像检测的发展趋势及存在的问题,结果表明融合多种成像方式和多信息成像方法将成为超声成像检测的重要发展方向,可为超声成像检测研究提供参考和思路。

Abstract:
In recent years, ultrasonic imaging testing technology has made rapid development and become a research hotspot in the field of nondestructive testing. This paper focuses on the development history, research status and progress of six ultrasonic imaging detection methods: acoustic time reversal imaging, ultrasonic phased array imaging, synthetic aperture imaging, total focusing imaging, dispersive guided wave imaging and ultrasonic multi wave imaging. It shows that acoustic time reversal imaging is an adaptive focusing imaging method, which is not applicable to nonlinear and dissipative media in principle, and can only be applied after appropriate improvement. Ultrasonic phased array imaging, synthetic aperture imaging and total focusing imaging are all phase control methods based on ultrasonic array, which can realize adjustable sound beam. With the development of electronic hardware and software technology, ultrasonic array imaging will develop towards three-dimensional real-time imaging. By analyzing the focusing and imaging characteristics of dispersive guided waves and multi waves, several methods to focusing and imaging of dispersive guided waves and multi waves by controlling the excitation signal waveform of each array element of the transducer are discussed. By analyzing the latest research progress of these imaging detection methods, the development trend and existing problems of ultrasonic imaging detection are studied and summarized. It is shown that the integration of multiple imaging methods and multi-information imaging will become an important development direction of ultrasonic imaging detection, which can provide reference and research ideas for the research of ultrasonic imaging detection.
