Ultrasonic control system using ultrasonic probes

The Ultrasonic System Research Institute has developed a new component inspection technology using megahertz ultrasonic oscillation based on its track record of analyzing ultrasonic data propagating on the surface of objects. This method applies the measurement and analysis technology of "sound pressure and vibration" through the control of original ultrasonic probe oscillation. We provide consulting and explanations of ultrasonic evaluation technology through the development of ultrasonic probes tailored to the purpose (vibration modes propagating on the surface of objects). This is an application of new ultrasonic oscillation control technology. By utilizing nonlinear phenomena related to megahertz ultrasonic propagation states that match the acoustic characteristics of the target object, it is possible to detect new features regarding the surface condition of the object. In particular, this fundamental technology serves as a new evaluation parameter for ultrasonic vibrations, utilized in surface inspection of substrate components and pre-evaluation of precision cleaning parts, leveraging the response characteristics derived from combinations of oscillation and reception. By measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves related to the propagation phenomena of surface elastic waves, we have enabled effective use tailored to the purpose (evaluation) through the construction and modification of logical models.

Ultrasonic Propagation Characteristics 1) Detection of vibration modes (changes in self-correlation) 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)

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibrations propagation through the measurement and analysis of ultrasonic propagation states. This classification method estimates linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequency (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to categorize effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type Furthermore, the variable type can be further classified into the following three types: 1: Linear variable type 2: Nonlinear variable type 3: Mixed variable type (dynamic variable type) There are numerous successful cases regarding the application of ultrasonic technology based on the development of devices, control settings, and inspections based on the above types. In particular, regarding stability and changes, detailed classification by frequency components has made it possible to efficiently set and adjust various conditions for the intended purpose and effect.
