材料光谱发射比的激光测量法研究

Measuring Method for Directional Spectral Emittance of Materials by Laser

材料的光谱发射比既是辐射度学中的重要物理量,又是热辐射式测温仪表中没有解决处理好的一个关键性问题。本文简述了近年来国内外在这一领域内的工作情况,提出并讨论了利用激光实时测定材料的光谱发射比,以便更准确地测出待测物体温度的方法。

The spectral emittance of object is important in radiometry. This paper reviews the measurement techniques of radiometric emissivity method and tntroduces a simple and convenient method of measuring object spectral emittance by laser.
