Ultrasonic tester NA, which allows for easy measurement and analysis of ultrasonic waves.

The Ultrasonic System Research Institute conducts consulting related to the use of ultrasound by applying feedback analysis technology based on multivariate autoregressive models, utilizing a technique for measuring, analyzing, and evaluating the propagation state of ultrasound. By organizing the measurements, analyses, and results obtained using ultrasonic testers in chronological order, we establish and confirm new evaluation criteria (parameters) that indicate the appropriate state of ultrasound for specific purposes. Note: Nonlinear characteristics (dynamic characteristics of acoustic flow), response characteristics, fluctuation characteristics, effects due to interactions, etc. By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various detailed effects related to vibrational phenomena, referencing statistical mathematical concepts. As a result, there is an increasing number of cases demonstrating the effectiveness of new nonlinear parameters related to the propagation state of ultrasound and the surface of the target object, such as changes in bispectrum and changes in autocorrelation. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on good confirmations.
