摘要尽管基于灯的加热装置具有广泛的实际应用、轻便性和成本效益，但在测量被加热材料上的温度方面的一个技术困难阻碍了基于灯的加热装置的发展。这种困难源于多色光源和从辐射（即光）确定温度的辐射温度计的组合。本研究开发的一种新系统通过专门测量加热材料的辐射克服了这种固有的困难，使我们能够在基于光的加热设备（电弧图像炉）中进行直接和原位的温度测量。测试表明，使用开发的系统，以及其有前途的潜力，在高温下，特别是在红外区域的发射率的测定温度测量的可靠性。图形摘要
ABSTRACT Despite a wide variety of its practical applications, handiness, and cost-effectiveness, the advance of lamp-based heating devices is obstructed by one technical difficulty in measuring the temperature on a heated material. This difficulty originates in the combination of a polychromatic light source and a radiation thermometer that determines temperature from radiation (i.e. light). A new system developed in this study overcomes this intrinsic difficulty by measuring exclusively the radiation from the heated material, allowing us to perform the direct and in-situ measurement of temperature in a light-based heating device (an arc image furnace). Test measurements demonstrated the reliability of temperature measurement using the developed system as well as its promising potential for the determination of emissivity at high temperature particularly in the infrared region.
