The optical path difference information used in the correction of the non-linear sampled infrared interferogram can effectively deduce the influence on the spectroscopy caused by the moving mirror of the interferometer. An optical path difference information getting method based on synthetic quadrature phase detector/demodulator was introduced and a FTIR spectrometer model based on this method was built. The optical path difference information getting method and the FTIR spectrometer system based on this method were also simulated. Experimental results show the effectiveness of this method.
