A new optical fiber Fabry-Perot (F.P.) temperature sensor is proposed and demonstrated. In particular, it can discern the rise from drop. With this sensor, change direction of be determined as a function time. The basic concept has been verified experimentally. results F.P. measurement compare well with an independent thermocouple measurement. To provide further insight, details experimentally observed interference fringes have also compared to computer simulation. Possible real-time implementations highspeed electronics are suggested.
