A Procedure for Measuring Thermal Emission Spectra at Ambient Temperature.

Abstract

This report describes preliminary work to collect the infrared spectral emission signatures of ambient temperature objects using a Fourier transform spectrometer operating in the 8-13 micrometer wavelength range. Details of the construction of a sample container are presented along with a description of the spectrometer, the controlling computer, and the data collection techniques and procedures. A system test, which is actually the ratio of two blackbodies at different temperatures, suggests that these procedures are valid. The emissivities of Krylon 1602 ultra-flat black paint, crushed fused quartz, and three types of cotton are presented.
