Research: I am developing highly-sensitive geophysical instruments using optical methods such as laser interferometry, and use them for seismic and geodetic observations. Long-baseline laser strainmeters, a compact absolute gravimeter, optical-fiber-linked seismometers and tiltmeters have been developed. Publications: A. Araya, S. Telada, K. Tochikubo, S.
