A system that controls the emission of two types of ultrasonic probes from a single channel.
Technology for controlling nonlinear phenomena of ultrasound.
The Ultrasonic System Research Institute has developed a technology to control nonlinear ultrasonic phenomena by utilizing the interactions generated from simultaneously oscillating two types of ultrasonic probes from one oscillation channel of a function generator. (Note: Nonlinear (resonance) phenomena refer to the resonance phenomenon of ultrasonic vibrations that occurs due to the generation of harmonics resulting from original oscillation control, achieving high amplitudes through resonance.) By optimizing the ultrasonic propagation characteristics of various materials to suit specific purposes, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology allows for the dynamic changes of surface elastic waves to be controlled according to their intended use. In practical terms, the use of multiple (two types of) ultrasonic probes for multiple (two types of) oscillations (sweep oscillation, pulse oscillation) generates complex vibration phenomena (original nonlinear resonance phenomena), achieving high sound pressure propagation states at high frequencies, or low frequency propagation states with high sound pressure levels tailored to the desired natural frequency.
