Design and construction of radiation thermometry systems under extremely nonequilibrium temperature condition

辐射测温，即基于物体发出的辐射亮度测量的非接触式测温方法，在科学和工业的各个领域都有应用。然而，由于背景辐射(光学噪声)很强，物体与加热器(如高强度灯)之间的温差很大，在极不平衡的温度条件下使用这种方法会遇到困难。我提出了一种通过引入噪声因子的参数来定量评估背景辐射的方法，并显著降低了背景辐射。在此基础上，建立了包括发射率补偿辐射测温在内的综合辐射测温系统的设计方法。

Radiation thermometry, that is, a non-contact temperature measurement method based on the radiance measurement emitted by an object is available in various fields of science and industry. This method, however, meets difficulties when it is used under the extremely nonequilibrium temperature condition that is caused by the large temperature difference between the object and heaters such as high intensity lamps, because of strong background radiance (optical noise).I proposed a method to evaluate background radiance quantitatively by introducing a parameter defined as a noise factor and to reduce it significantly as well. Based on this method, I established a method for designing an integrated radiation thermometry system including the emissivity-compensated radiation thermometry.
