| 摘 要： | 讨论了表面辐射测温方法的设计中所包含的几个基本问题:辐射的光谱和方向复杂性问题、光学设计问题以及电路设计问题,给出了具有普适意义的辐射测温基本分析式。比较了绝对辐射测温方法和相对辐射测温方法,指出前者须做标定,并且不宜进行温度场测量;后者无须标定,适合于温度场测量。

| Abstract: | The fundamental issues in the design of surface temperature measurement method via radiation approach are discussed in this article, such as the spectral and directional complicacy of thermal radiation, the optical design, and the electrocircuit design. A generalized equation for the analysis of temperature measurement method via radiation approach is proposed. The method of absolute value and relative value is compared. Calibration should be made in the absolute value method but not in the relative value method. The former method is not suitable for the measurement of temperature fields while the latter method is. |
