FIELD: measuring technique.
SUBSTANCE: Fourier spectrometer has case, beam splitter, compensator, reflectors and photoreceivers. Parallelogram device is disposed in case. Beam splitter, compensator and reflectors are disposed inside parallelogram device. One reflector is fastened to parallelogram device for simultaneous movement along light flux and at side direction from light flux. Fourier spectrometer provides registration of interference pattern of tested radiation and the Fourier transform for calculating spectra/spectrum.
EFFECT: reduced sizes and weight; widened are of applications; improved precision of measurement.
