Abstract

The thermal radiation reflection properties of real material surfaces tend to be directional, which leads to inaccuracies in existing methods for measuring the diffuse inner surface temperature of cavity-like objects. In this article, we propose a method for measuring the temperature at the inner surface of cavity-like objects that describes the interreflection based on the bidirectional reflectance distribution function (BRDF) and on the Monte Carlo ray-tracing method (MCM). The effects of measurement angles and surface roughness on temperature measurement errors have been analyzed through simulation calculations and experiments. The results show that the inner surface structure and reflection characteristics make the error change at different measurement angles. Compared to the actual methods in use, the results obtained for the proposed method for the inner surface with directional reflection allow a reduction in the maximum relative error from 14.2% to 0.8%.

具有定向反射特性的类空腔物体内表面温度测量误差及校正方法研究

实际材料表面的热辐射反射特性往往具有方向性，这导致现有的测量类空腔物体漫射内表面温度的方法不准确。在本文中，我们提出了一种基于双向反射分布函数（BRDF）和蒙特卡罗射线追踪法（MCM）来描述腔状物体内表面互反射的温度测量方法。通过仿真计算和实验，分析了测量角度和表面粗糙度对温度测量误差的影响。结果表明，在不同的测量角度下，内表面结构和反射特性导致了误差的变化。与实际使用的方法相比，对于有方向反射的内表面，本文方法的结果允许将最大相对误差从14.2%降低到0.8%。
