title: [Error analysis and calibration method of complex spectrum of Fourier transform infrared spectrometer].
abstract: The phase shift in complex spectrum of Fourier transform infrared (FTIR) spectrometer was discussed. A rigorous derivation showed the relation between the phase shift and complex spectrum. The reason for the radiation offset in FTIR measurement was analysed. The present article presents a calibration method of FTIR complex spectrum, which can adjust the radiation offset. The comparison between experiment data and theoretical computation showed that the method is precise.
