Paper Abstract

Quantitative spectroscopy requires detectors exhibiting linear response with respect to intensity. Photoconductive detectors commonly used for FT-IR spectroscopy (e.g., an MCT) typically exhibit a non-linear response which distorts the true spectrum. In order to effectively use these detectors for quantitative work it is necessary to employ hardware or software corrections to linearize the detector response. The advantages and disadvantages of correcting detector response are discussed.
