Abstract :
Red colored photoluminescence (PL) images have been observed from Cr doped garnet, Y3Al5O12 (YAG) sensor using a CCD camera system. PL image from YAG sensor increases linearly with temperature from 25 to 250degC. Temperature can be measured using PL image from Cr doped YAG sensor. Image processing techniques, such as line scanning, histogram and integration of brightness are effective for two-dimensional fluorescence thermometer application.
