Abstract

Advances in the area of Optical Fiber Thermometry (OFT) are leading to more accurate temperature measurements in high-temperature environments. A typical OFT application is when the tip of an optical fiber is inserted into an environment where the temperature is to be measured. The other end of the fiber is attached to an optical system where light from the fiber is measured (see Figure 1). From the light emission measurements, the temperature at the heated tip of the fiber can be inferred.¹
