摘要：
A radiometric instrumentation was constructed and utilized to measure the hemispherical radiation reflected by the observed object being irradiated by a parallel infrared beam. The results of initial laboratory investigation of spectral hemispherical emissivity of limestone and hematite samples are reported. The reported measurements have been performed with spectral resolution of about 0.2 mu m in the thermal infrared (TIR) band (8-14 mu m).
