The purpose of this paper is to demonstrate a novel technique for imaging 2D temperature distributions using rise-time analysis from luminescence exhibited from a Y<sub>2</sub>O<sub>3</sub>:Eu thermographic phosphor. In phosphor thermometry, it is usually the lifetime-decay temporal response that is used to determine temperature; the rise component is usually ignored. We claim to be the first to obtain 2D thermal imaging using the rise-time response. This was demonstrated using flame impingement experiments. A 1 Mfps state-of-the-art high-speed Shiamadzu Hypervision camera was used to capture the phosphors' temporal response, and was later processed in Matlab. The resulting thermal map clearly indicated a variation in temperature and showed an uncertainty of 20% at 400 °C. This is relatively high, and suggestions to improve this are proposed. A calibration of rise time versus temperature is taken between 200 and 700 °C. This paper builds on previous work in the field, and the results presented in this paper confirm the extended temperature sensing capability of Y<sub>2</sub>O<sub>3</sub>:Eu using rise-time characteristics. |
