摘要

本文推导并实验证明了一种在热发射测量中求解发射率/spl - epsiv/和温度T的辐射测量方法。通过分束器和反射镜，利用被观测源自身的发射作为非相干探测光束。对几种耐火材料进行了137 GHz至1500/spl℃的测量。

Millimeter-wave radiometer measurement of emissivity and temperature by thermal return reflection (TRR)

A radiometric method for resolving the emissivity, /spl epsiv/, and temperature, T, in thermal emission measurements is derived and experimentally demonstrated. The viewed source's own emission is utilized as an incoherent probe beam by means of a beamsplitter and return mirror. Measurements of several refractory materials at 137 GHz to 1500/spl deg/C were carried out.
