Thick Part Inspection using Volume Focusing and Large Aperture Phased Arrays
In the nuclear maintenance field, there are cases where accessing a location where flaws must be detected can only be done through a long UT path. In such cases, not only the lateral resolution, but also the inspection scanning time becomes an issue. This paper presents an original solution based on using large apertures and Volume Focusing, providing significant gains in inspection time by factors between 5 to 10 times in comparison to conventional phased array. This method has a very high detection ability and lateral resolution, where small flaws can be detected and separated from each other, and eventually sized.
