HOME > National Metrology Institute of Japan
As the national metrology institute (NMI), we are focusing on the development and dissemination of measurement standards, promotion of measurement standards utilization, development of measurement technologies related to measurement standards, legal metrology work and training of experts. Our activity covers engineering, physical, material, and chemical measurement standards. It also covers development of measurement and analytical instrumentation. We also coordinate international activities on metrology standards as a national representative.
AIST has developed a new digital X-ray imaging device that enables digital inspection of infrastructures. The developed device can be driven with batteries. Combination with a battery-powered X-ray source enables X-ray inspection up to 10 cm thick iron objects.

AIST has developed a circuit measurement method to measure the transmission characteristics of high frequency transmission lines (coplanar waveguides). The developed method enabled high precision measurement of the characteristics of coplanar waveguides fabricated using printing technology in the ultra-high frequency range over 300 GHz.
