Computation of the similarity between MIR and FT-IR data. The compared wavenumbers refer to 2790 cm−1 (laser 1), 2926 cm−1 (laser 2) and 3350 cm−1 (laser 3). The data are mapped and aligned to each other. A region of interest (ROI) is defined for better visibility. Each image (RIO MIR and ROI FT-IR) consists of the mentioned wavenumbers. The similarity of the corresponding data sets is ~ 75%. Differences between the images are predominantly due to intensity differences.
