摘要
This work aims to achieve contactless absolute-temperature measurements of infrared-semi-transparent solids using an infrared thermal and spectroscopic imaging technique. The multispectral thermotransmittance coefficient fields in the 3-5 mu m wavelength range for Sapphire, KBr, and Silicon are determined to be 6 x 10(-4) K-1, 4 x 10(-4) K-1, and -3 x 10(-3) K-1, respectively. The most interesting result is the high temperature-dependent transmittance coefficient in the middle wave infrared region. With these coefficients, the absolute temperature fields in a range from room temperature to 140 degrees C are shown.
