中文摘要:
      超声相控阵全聚焦成像技术基于接收信号后处理的思想,对检测回波数据进行离线分析成像,是超声检测领域里的一项新技术。因其成像分辨率高、覆盖面广、对小缺陷灵敏度高等优势,在航空航天、高铁、石油管道、核电站等工业领域已有初步应用。文章介绍了全聚焦成像技术的检测原理及优缺点,介绍了其国内外发展历程,总结了研究热点及发展趋势。
英文摘要:
      Total Focusing Method (TFM) for ultrasonic phased array imaging is a new technique in ultrasonic detection. It is based on the idea of echo data off-line analysis for post-processing of received signals. Because of its high imaging resolution, wide coverage, high sensitivity to small defects and so on, this technique has been preliminarily applied in the fields of aerospace, high speed railway, oil pipelines, nuclear power plants and others. This paper introduces the detection principle, advantages and disadvantages of the total focusing method for ul-trasonic phased array imaging, summarizes the development situation at home and abroad, and sums up the research hotspots and the development tendency.
