Abstract

This report describes the preliminary work to collect the ir spectral emission signatures of ambient temperature objects using a Fourier transform spectrometer operating in the 8–13-μm region of the electromagnetic spectrum. 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, indicates that these procedures are valid. The emissivities of Krylon 1602 ultraflat black paint, crushed fused quartz, and three types of cotton are presented.
