In time-modulated Fourier Transform infrared imaging spectrometers (FTIR), a sharp, disturbance peak can appear in the spectral data under certain circumstances. The position of the peak is not fixed and the magnitude of the peak varies considerably. The existent of this disturbance peak will have a significant impact on the subsequent spectral data process. In this paper, the appearance of this phenomenon is analyzed and the reasons are explored. Through the analysis, the source of the disturbance is identified and named as "glitch peak". A corresponding solution is proposed to effectively eliminate the "glitch peak" disturbance peak in time-modulated FTIR imaging spectrometer. The effectiveness of the analysis and processing method is experimentally proven.
