Popis:	We have demonstrated the performance of a fiber-optic intensity sensor for temperature measurement. The method measures the change in absorption with the temperature of light reflected from a thin silicon film deposited on the end of an optical fiber. Our single-ended sensing approach requires that the incident light intensity be reflected from both film surfaces and that these reflected signals re-enter the fiber. Simplifications in sensor fabrication have been shown to yield sensitivity comparable to that reported by other authors. Calibration data on the sensor is presented up to 400°C. Potential applications of the method are discussed.
