Megahertz ultrasonic oscillation (sweep oscillation, pulse oscillation) system
Technology for optimizing the resonance and nonlinear phenomena of ultrasonic vibrations through megahertz oscillation control of an original ultrasonic oscillation control probe.
The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface acoustic waves through ultrasonic oscillation control techniques. By confirming the basic acoustic characteristics of ultrasonic waves (response characteristics, propagation characteristics) for various targets (water tanks, transducers, probes, fixtures, objects, etc.), we realize ultrasonic propagation states tailored to specific applications through oscillation control. Using two or more types of nonlinear resonant ultrasonic oscillation control probes, we dynamically control high-frequency propagation states above 900 MHz through the setting of oscillation conditions for sweep oscillation and pulse oscillation (note), resulting in high sound pressure level resonance phenomena and the generation of harmonics (nonlinear phenomena of 10th order and above). Note: Precision cleaning examples Sweep oscillation: 700 kHz – 20 MHz, 15 W Pulse oscillation: 13 MHz, 8 W 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) Note: "R" statistical processing language autcor: autocorrelation analysis function bispec: bispectrum analysis function
