Optical throughput and optical path length are key parameters to obtain high signal to noise ratio and sensor sensitivity for the detection of skin tissue components based on short wavelength infrared ...

We present the first controlled-environment measurements of the optical path-length change response of telecommunication submarine cables to active seismic and acoustic waves. We perform the ...

The academic information network (SINET)[i], built and operated by NII, serves as Japan’s nationwide academic information infrastructure for universities and research institutions. Through regional ...
