Since the kinetic energy of material particles in a damaged area would suddenly change when ultrasonic waves encounter the damage, the new algorithm embedded in the wave visualization technique is aimed at monitoring the kinetic energy variations of all points in an inspection region to construct a damage diagnostic image. To validate the new algorithm, three kinds of surface damages on the center of aluminum plates, including two non-penetrative slits with different depths and a circular dent, were experimentally inspected. From the experimental results, it can be found that the new algorithm can remarkably enhance the quality of the diagnostic image, especially for some minor defects.<\/jats:p>","DOI":"10.3390\/s141120439","type":"journal-article","created":{"date-parts":[[2014,10,29]],"date-time":"2014-10-29T11:19:24Z","timestamp":1414581564000},"page":"20439-20450","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["An Efficient Algorithm Embedded in an Ultrasonic  Visualization Technique for Damage Inspection Using  the AE Sensor Excitation Method"],"prefix":"10.3390","volume":"14","author":[{"given":"Yaolu","family":"Liu","sequence":"first","affiliation":[{"name":"College of Aerospace Engineering, Chongqing University, Chongqing 400044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riu","family":"Goda","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Chiba University, Chiba 263-8522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoshi","family":"Samata","sequence":"additional","affiliation":[{"name":"JAL Engineering Co.
