弥散介质条件下主动式双激光测温方法性能分析
Performance Analysis of Active Dual-laser Temperature Measurement Method under Dispersive Medium Conditions
摘要
Abstract
In industrial field environments,traditional radiation thermometers must penetrate diffuse media or isolation windows to remotely measure the surface temperature of a target,which significantly affects the temperature measurement results.By adopting the active laser radiation temperature measurement technology,experiments are designed with quartz glass as the interfering medium to measure the true surface temperature under different transmittance conditions,and the temperature measurement performance differences between traditional radiation thermometers and the active temperature measurement system are compared and analyzed.Experimental results show that the average temperature measurement deviation of the active temperature measurement system is 3.6 K under interference of different transmittances.Under the same transmittance conditions,the average deviation of the traditional LP4 radiation thermometer is 3.7 K,and its deviation increases gradually with the rise of measured temperature,which verifies that the active system possesses better penetration capability than traditional radiation thermometers.The results indicate that the active temperature measurement system can maintain high measurement accuracy even when the emissivity of the measured sample is unknown,and is theoretically capable of eliminating the transmittance influence along the optical path.关键词
