Paper Abstract

A laboratory version of a novel temperature sensor based on a Fiber Fabry Perot (FFP) interferometer and the wavelength control of a temperature stabilized laser diode is presented. The FFP with finesse of about 10 is observed in its reflected light at a fixed interference order to which the laser wave-length is continuously tuned by a corresponding variation of the injection current. The sensor in its present state allows for a resolution better than 0,1°C and a measuring interval of about 20°C. These properties along with the short and thin sensor tip geometry makes it an attractive device for medical applications such as continuous temperature measurements in hyperthermia systems.
