摘要
In optical frequency domain reflectometry the refractive index of a liquid is determined from the ratio of the light reaching an optical receiver, including the light from a light source reflected back from square-cut, open-ended optical fibre immersed in the liquid, for two different modulation frequencies of the source, to compensate for ambient temperature fluctuations.
