要約(英語): Ultrasonography, which is one of the quality inspection methods, is able to inspect inner material in a non-destructive. However, with the conventional method, we can discriminate existence of inner defects of the measurement object, but it is difficult to detect the position of inner defects as three-dimensional information. Thus in this study, we focused ultrasonic holography, which is a method to detect of the sound source position. The purpose of this study is building a system to obtain three-dimensional information inside the material instantly by analyzing ultrasonic holography with the two-dimensional sound distribution which appears on the measurement object surface by penetrating through objects of ultrasound. As problems of ultrasonic holography, there are a long measurement time and appearance of Aliasing Image. Therefore, in our study, we suggested a method to obtain sound distribution by Speckle Interferometry, as method to solve two problems at once.
