The reason that fluorescence lifetime of optical fiber fluorescence temperature measuring system exists nonlinear error is analyzed. In order to realize error compensation to improve the detec- tion accuracy, the paper adopts fuzzy strategy for nonlinear error compensation of the fluorescence life- time to eliminate the influence of errors. Use simulation model established by Matlab and test data of actual system to verify the experimental result, and it shows that temperature measurement system can effectively improve the stability and accuracy of fluorescence lifetime. So the research has important significance for improving the accuracy and robustness of the fluorescence optical fiber temperature measuring system.
