STATIC FOURIER-TRANSFORM SPECTROMETER AND METHOD FOR OPERATING THE STATIC FOURIER-TRANSFORM SPECTROMETER

摘要

The invention relates to a static Fourier-transform spectrometer (1) comprising a radiation source (4) which is designed to emit infrared radiation during operation of the static Fourier-transform spectrometer, which propagates, during operation, along a ray trajectory (5) of the static Fourier-transform spectrometer, comprising a sample path (14) and a reference path (15), a sample (7) which is simply arranged in the sample path and, as such, during operation, interacts with the infrared radiation of the sample path, and an interferometer section (3) which is designed to produce a sample interferogram (27) of the sample path following the interaction with the sample and a reference interferogram (28) of the reference path, and comprises a detector (11) which is designed to simultaneously pick up the sample interferogram (27) and the reference interferogram (28), the statistical Fourier-transform spectrometer being designed to determine a sample spectrum (20) from the sample interferogram and a reference spectrum (21) from the reference interferogram by means of respectively a Fourier transform, and to correct the sample spectrum with the reference spectrum.
