Optical Lattice Clock
Shimadzu partnered with a joint research group including Masao Takamoto, Senior Research Scientist at RIKEN, and Professor Hidetoshi Katori from the Graduate School of Engineering, The University of Tokyo (Team Leader and Chief Scientist at RIKEN), to develop ultra-accurate transportable optical lattice clocks with 18-digit accuracy. The two optical lattice clocks were installed on the ground floor and observation deck (450 m) of Tokyo Skytree to determine whether the difference in time measured between the two clocks was consistent with that predicted by the general theory of relativity based on the difference of elevation measured by the Geospatial Information Authority of Japan. The experiment successfully demonstrated the theory of general relativity with accuracy approaching conventional satellite-based methods.
The results also verified that relativistic sensing is possible outside of a laboratory environment, which achieved a major step toward the practical use of optical lattice clocks. In the future, the clocks are anticipated to be used as technology for monitoring movements of the Earth’s crust associated with plate tectonics, volcanic activity, and other phenomena.
