| Popis: | A moving (mechanical) two-dimensional Hadamard encoding mask has been employed with a Fourier-transform infrared (FT-IR) spectrometer to combine imaging in two spatial dimensions with the spectral dimension as a form of three-dimensional spectrometry in the mid-infrared and near-infrared spectral regions. Chemical images at chosen wavenumbers and mid-infrared spectra of individual pixel positions in the image have been obtained with acceptable signal-to-noise ratios and reasonable data-acquisition times. |
