Remote thermometry via laser-induced fluorescence (LIF) of a thermographic phosphor (doped refractory oxide) is a sensitive and potentially high precision technique of growing usefulness in thermal metrology. A typical LIF measurement system consists of detection, waveguide and signal analysis hardware. The systematic errors due to each of these components must be evaluated in order to arrive at an overall error budget for the measurement. In this paper, we consider the problems arising in calibration and characterization of the instrumentation used to monitor a fluorescing Y2O3: Eu phosphor.
