Abstract :
Two-dimensional photoluminescence (PL) image from sensor material is evaluated for fluorescence thermometer application. Two dimensional PL image is observed using CCD video camera under blue and/or UV LED illuminations. Red colored PL image can be observed from ruby sensor under illumination of blue LED. Brightness of red signal of PL image from ruby sensor varies linearly with temperature from 20 to 100degC Temperature can be measured based on brightness of PL images from fluorescence thermo-sensors. Video images processing technique (line scanning of intensity, histogram and integration of signal intensity) is found to be effective for fluorescence temperature measurement using phosphor sensors.
