Abstract

We have developed a novel thermometer based on the small temperature-induced changes in the optical reflectivity of metals and semiconductors. A nulling optical bridge has been constructed which reduces the temperature measurement to the shot noise limit of the detector. Under ideal laboratory conditions, we have demonstrated a temperature resolution of 0.2°C.
