| Abstract: | The method of data processing for interferogram is discribed in this paper.The interferogram of a mercury lamp has been measured in experiment by means of ultraviolet Fourier Transform Spectrometer in developing.The apodization function that we have chosen is four term Blackman Harris wihdow function and a fitting polynomial has been used for phase correction of Fourier Transform spectra based on the least square method.The ultraviolet emission lines of high precision have been obtained by use of this method. |
