Metrology and Measurement Science Establishing common scales for industrial measurement and dissemination of advanced evaluation technology for administration measures

Setting measurement standards and developing intellectual techno-infrastructures for measurement, testing, and certification to support technological innovation and a fair and secure society

Measurement is necessary for designing and developing products as well as for testing and certifying their qualities. It serves as a driving force to maintain Japan's industrial competitiveness, and as an intellectual technoinfrastructure for sharing technical policies to maintain the security of society and the lives of individuals, preserve the environment, and maintain energy and resources. AIST develops and maintains national measurement standards in order to ensure global acceptability of consistency, of relevant technologies, and is systematically developing measurement technologies from the standpoint of intellectual infrastructure.

Outline of priority strategies

Development of new national measurement standards and dissemination of measurement standards to industrial and social users

AIST develops new national measurement standards required to specifically support "green innovation" that promotes energyefficient technologies, also "life innovation" to ensure food safety, and industrial competitiveness such as facilitating the application of advanced industrial technologies to Japanese industry, in response to the rapidly growing global market, and keeps providing national calibration services to users.

Contribution to and leadership in the global metrology system

Our international activities lead the global metrological system for international mutual acceptance of measurement standards and measuring instruments and global standardization on measurement technologies. Included is the cooperation for the redfinition of basic units such as the kilogram and second. Our dissemination activities also cover the training of metrological experts and verification experts for domestic industrial and regulatory activities, and the metrological administration officers based on the measurement law of Japan.

New Research Results

Development of a National Measurement Standard for Calibration of Radio-frequency Power Meters in an Ultrahigh-frequency Band

AIST has developed a national measurement standard for calibration of ultrahigh-frequency power meters in collaboration with NICT. An isothermal control technology for the measurement of RF power and DC power converted into heat and a technology for their equivalency evaluation have been developed. These technologies were used to achieve a national measurement standard for the calibration of RF power meters in the 110 to 170 GHz band. In addition to improving the reliability of electromagnetic interference testing for millimeter-wave automotive radars, it is expected to contribute to the development of security systems in airports, evaluation technology for electromagnetic shielding materials, and the ultrafast semiconductor field.

Proposal of a New X-ray Non-destructive Inspection Method for Industrial Use

AIST and Tohoku University have demonstrated that internal defects such as voids in the encapsulant of semiconductor packages, which could not be detected by conventional X-ray non-destructive inspection, can be observed using X-ray Talbot interferometry. X-rays are used for non-destructive inspection of industrial products. However, it has been difficult to inspect materials such as resins, which have small X-ray absorption coefficients, using conventional X-ray absorption images. With X-ray Talbot interferometry, X-ray phase images can be recorded using a laboratory use X-ray source. AIST proposed its use for the observation of defects in electronic components and found that internal defects in resins can be observed and this is expected to contribute to the sophistication of quality control.

Metrology Institute of Japan

Precision measurement technologies and metrological traceability supporting R&D, quality control, and international trade

The Metrology Institute of Japan is engaged in technical development and improvement of national metrology standards, and also calibration and testing services using the developed technologies. Furthermore, we are pioneering in advanced research and development on measurement and analysis technology, which is a common infrastructure for various fields, aiming at world-leading research achievements. Through these activities, we are taking the initiative in implementation and management of domestic metrological system from a technical viewpoint so that anyone can choose and utilize a reliable measurement guaranteed by metrological traceability according to cost and time, thereby contributing to the smooth progress of Japan's economic activities in the global market.

Evolution from measurement into analysis with the dissemination of advanced instruments

From an historical perspective, new scientific and technical disciplines and new industries have often appeared after the invention of novel measurement instruments. For instance, the invention of the scanning tunnel microscope created the modern discipline of nanotechnology. It is said that instrumental observation is the origin of science and technology. Although science and technology are indispensable for our present way of life, we should also be aware of their power for harm. The survival or destruction of the human race depends on how we create and control industries. As such, observation only is insufficient. We have to analyze measurement results, find ways to solve each problem, and explain the findings in a meaningful way. In other words, analytical results should be extracted from measurements. We carry out five strategic action plans by expanding three analytical instrumental frontiers as shown on the right-hand side.

Measurement Solution Research Center

Developing measurement technology solutions for better productivity to keep the safety and security of industry and society.

Our mission is to provide the solutions on time to various problems arising at production sites and in society by integrating the research results of measurement, instrumentation and relating technologies. As a means to achieve this, we are promoting the collaboration with "meisters" who are the specialists at the production sites in private sectors and well informed about the measurement problems there (we call this approach as "meister system"). We also take a consortium-type approach if the problems are relatively common in a certain field of industry and society. By accumulating the cases which resulted in the solutions and by sending out the proper information, we contribute to the improvement of the productivity to keep the safety and security of industry and society.
