“…Отношение сигнал/шум в приборе зависит от освещенности детектора, изменения температуры ФПУ при самонагревании и от температуры окружающей среды. Такие закономерности могут быть устранены благодаря введению новых температурных коэффициентов для калибровки спектральных погрешностей [5].…”

“…The detector image as well as the detector temperature are read out at a frequency of 50 Hz for quantitative analysis (see Section 6.1 ) and at 200 Hz for qualitative high-speed measurements (see Section 6.2 ). After an algorithmic correction accounting for the microbolometer temperature according to [ 13 ], the spectra are calculated. The absorption spectra for the calibration are determined using Equation ( 2 ).…”

“…Static single-mirror Fourier transform spectrometers (sSMFTS) [ 11 , 12 ] show a rugged and compact design with high SNR, as they work without moving parts and still are based on the Fourier transform principle. Temperature effects can be compensated with suitable algorithmic corrections [ 13 ]. Additionally, sSMFTS show high measurement frequencies of up to 200 Hz [ 14 ] allowing the monitoring of fast chemical reactions or of gases propagating at very high flow rates.…”
