In many industries and engineering fields, there are a lot of demands for non-destructively measuring and monitoring some characteristics such as mechanical properties, temperature, and defects inside a material. We have been pursuing the study on quantitative and noninvasive measurement method utilizing ultrasound to meet these demands. Ultrasound is a very attractive and effective method for non-destructively evaluating materials and products. We are trying to develop novel non-contact monitoring system at high temperature and to create measurement theory by taking advantage of laser ultrasonic, and air-coupled ultrasound.
