摘要

The commercially available model MR254/AB FT-IR spectrometer is based on a dual-beam interferometer design. One arm of the dual-beam interferometer uses an internally controlled blackbody source for passive standoff airborne applications. This configuration with an internal blackbody produces a variety of output spectra that do not necessarily follow the output spectral conventions of a single-beam FT-IR spectrometer. The differences between a dual-beam and single-beam instrument are documented with eight examples using the radiance equation that models the dual-port MR254/AB spectrometer spectral response in terms of internal blackbody, gas cell, and background blackbody spectroradiometric temperatures.
