INFRARED FOURIER SPECTROMETER WITH REMOTE FIBER PROBE
This article describes an experimental Fourier transform infrared (FTIR) spectrometer equipped with fiber optic probes. The device enables to measure remotely the spectral characteristics of objects under study (various fluids, such as fuels, lubricants, various chemicals, etc.) using infrared fiber optic probe. The measurements are, namely, the transmission, reflection and attenuated total reflection spectra. The authors analyze the composition and arrangement of optical-mechanical and electronic parts of the proposed Fourier spectrometer, and their main units. The results of test measurements of basic spectral characteristics of the instrument, and also the recorded spectra of known substances show the operating capability of such a device
