- Technology for controlling nonlinear vibration phenomena through oscillation control of original ultrasonic probes -

The Ultrasonic System Research Institute has developed oscillation control technology based on the acoustic characteristics of probes through the manufacturing technology of original ultrasonic probes. This has evolved into technology for controlling the nonlinear vibration phenomena of surface acoustic waves. The key point is the optimization control method for ultrasonic oscillation control tailored to the propagation characteristics of surface acoustic waves on the surface of ultrasonic elements and their intended use (conditions for combining sweep oscillation and pulse oscillation). To achieve this, it is important to dynamically evaluate the propagation state of ultrasound through operational verification of the ultrasonic propagation characteristics of the original probe (sound pressure level, frequency range, nonlinearity, dynamic characteristics, etc.). In particular, it is necessary to measure, analyze, and evaluate the dynamically changing oscillation characteristics of the ultrasonic probe (or element) and the oscillator (function generator) regarding their transmission and reception characteristics.
