Abstract :
Fluorescence thermometer using photoluminescence (PL) images from sensor is studied for two-dimensional and non-contact temperature measurement. Visible light PL images can be observed clearly from fluorescence thermo-sensors using CCD camera with green, blue and/or UV excitation. Temperature can be measured based on temperature dependence of brightness of the PL images. Video images processing technique is found to be effective for fluorescence temperature measurement based on PL images from the crystal and composite sensors.
