Omrane, A., Ossler, F., Alden, M., Gtoransson, U. and Holmstedt, G., 2003. Surface Temperature Measurement Of Flame Spread Using Thermographic Phosphors. Fire Safety Science 7: 141-152. doi:10.3801/IAFSS.FSS.7-141
ABSTRACT
A technique based on remote measurements of surface temperature in connection to fires is presented. Pulsed ultraviolet laser radiation at 266 nm and 7 ns duration was used to excite a thermographic phosphor, Mg4FGeO6: Mn, which was adapted on the surface of the investigated material. The laser-induced emission from the phosphor was recorded. A calibration of the phosphorescence lifetime and spectral properties against temperature allowed surface temperature measurements between 25°C and 500°C. The method was tested and compared with thermocouple measurements on burning materials such as lowdensity fiberboards and polymethylmetacrylate.
