Bolometric detector and filter arrangement used for the power calibration measurements.
Diagram of the globar showing the components and the active region.
Globar temperature as a function of the electrical power measured using an IR thermometer (crosses) with temperature extrapolation (solid line).
Comparison of globar spectrum (dashed curve) measured using the FTS compared to the theoretical Planck’s distribution (solid curve). This figure was used to determine the CF associated with the fall off of the signal toward the higher frequency cutoff.
Comparison power spectra of (solid curve), globar (dashed curve), and Hg lamp (dotted curve) as measured using the FTS.
