Dynamic control technology of megahertz ultrasound - Nonlinear control technology of ultrasound using multiple function generators.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing multiple function generators. This technology enables the control of nonlinear ultrasonic phenomena through oscillation with several different waveforms (sweeping). Note: Nonlinear (resonance) phenomena By generating harmonics of the 10th order or higher through original oscillation control and resonating with low-frequency vibration phenomena, the generation of high-amplitude harmonics has been achieved, resulting in nonlinear (resonance) phenomena of ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various components according to their intended purpose, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology dynamically controls the changes in surface elastic waves according to the intended application. Ultrasonic Oscillation Control Probe Measurement and analysis range: 1 Hz to 200 MHz Oscillation range: 0.5 kHz to 25 MHz Ultrasonic propagation range: 5 kHz to over 900 MHz (analysis confirmed) Ultrasonic propagation characteristics: 1) Detection of vibration modes 2) Detection of nonlinear phenomena 3) Detection of response characteristics 4) Detection of interactions
