Recently, the Guangdong Association for the Promotion of Measurement and Control Technology and Equipment Application and the Guangzhou Instrument and Meter Society organized the acceptance and scientific and technological achievements appraisal of the scientific and technological project "18 MHz High Frequency Ultrasonic Power Measurement and Calibration Instrument" of our institute
.
Experts from South China University of Technology, Guangzhou Institute of Electronic Technology, Chinese Academy of Sciences, Guangdong Institute of Machinery, Shenzhen Institute of Metrology and Quality Inspection, Guangzhou Institute of Metrology and Inspection Technology, Jiangmen Quality Metrology Supervision and Inspection Institute, and Guangzhou Institute of Mechanical Design The group unanimously agreed to pass the acceptance of the science and technology project, and believed that the project had reached the international advanced level in terms of the multi-frequency point output ultrasonic power source with the highest output frequency of 18.
The scientific and technological project "18 MHz High Frequency Ultrasonic Power Measurement and Calibration Instrument" carried out research on 18 MHz high frequency ultrasonic power generation and measurement technology, focusing on breaking through the three frequency points (the highest output frequency) based on the Y-36o cutting method of lithium niobate single crystal wafers.
18.
9 MHz) ultrasonic transducer technology and a correction method suitable for the radiation pressure method to measure high-frequency ultrasonic power.
A high-stability high-frequency ultrasonic power source and a special absorption target measuring device have been developed, which are easy to use and stable
.
At present, the project has been authorized with 1 invention patent and 1 utility model patent, 1 academic paper published, and independent intellectual property rights
