VISUALIZATION OF SURFACE TEMPERATURE BY THE LIFETIME-BASED PHOSPHOR THERMOMETRY USING A HIGH-SPEED CAMERA

摘要
A surface temperature inside an optical engine with or without heating the intake gas was measured using the phosphor thermometry (PT) in view of a combined measurement of the velocity and temperature map. The temperature distribution was measured by the PT using only 3 or 10 images, which were recorded by the non-intensified high-speed CMOS camera, by taking into account the local pixel nonlinearity. The temporal standard deviation of the decay constant was 0.17−0.33% and it changed 0.15% by the position, indicating that the nonuniformity of the pixel nonlinearity was large. With the local calibration, the spatial fluctuation of the measured temperature was 0.10−0.53°C. This technique was applied to temperature measurement in the optical engine, resulting in reasonable temperature maps.
