- 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. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response) 4) Detection of interactions (analysis of power contribution rates)

Dynamic Control Method for Megahertz Ultrasound Based on Classification Techniques Related to Ultrasonic Propagation Phenomena

The Ultrasonic System Research Institute has developed a classification method for ultrasonic propagation phenomena based on the analysis results of ultrasonic sound pressure data and changes in the bispectrum. This classification has been applied to Shannon's juggling theorem to develop a "dynamic control method for megahertz ultrasound." This technology is being offered for consulting proposals and implementation support. To utilize ultrasonic propagation phenomena stably and efficiently, it is necessary to examine the response characteristics and interactions related to conditions other than oscillators and transducers, as well as to develop dedicated tools. By examining oscillation waveforms and control conditions, new ultrasonic effects (Note 1: Original nonlinear resonance phenomenon) can be discovered. Utilizing ultrasonic phenomena primarily driven by nonlinear effects according to specific purposes enables highly efficient use of ultrasound. In particular, there has been an increase in achievements in nanolevel ultrasonic technology. Note 1: Original nonlinear resonance phenomenon The generation of harmonics caused by original oscillation control, which is realized at high amplitudes due to resonance phenomena, results in the resonance phenomenon of ultrasonic vibrations.
