A novel two dimensional temperature measurement method was developed using a lifetime of luminescence. Temperature effects on the luminescent lifetime and intensity of various luminophors were investigated. Using temperature sensitive luminescent materials, two measurement techniques were developed, one calculated the decay ratio from two images captured by a sensitive cooled-CCD sensor, and the other estimated the decay rate from several sequential images recorded by an non-intensified high speed CMOS camera during a single decay. A temperature distribution on the solid surface of high temperature was successfully measured in an optical gas engine. In addition, beyond an initial plan, a combined measurement of temperature and velocity distribution was performed. We simultaneously measured the temperature and velocity distribution of a double natural convection driven by buoyancy and Marangoni force.

提出了一种利用发光寿命进行二维温度测量的新方法。研究了温度对不同发光体发光寿命和发光强度的影响。利用温度敏感的发光材料，发展了两种测量技术，一种是从敏感的冷却CCD传感器捕获的两幅图像中计算衰减率，另一种是从非增强型高速CMOS相机在一次衰变过程中记录的几幅连续图像中估计衰减率。在一台光学燃气发动机上成功地测量了高温固体表面的温度分布。此外，除了最初的计划外，还进行了温度和速度分布的联合测量。我们同时测量了浮力和Marangoni力驱动的双自然对流的温度和速度分布。
