  • Publication number: 20200056941
    Abstract: A superimpose Fourier Transform method applied to spectroscopy and imaging is provided in this invention. Raw signals are acquired by various spectrometric detectors. The acquired data are processed by Fourier Transform with a superimposed function to superimpose the transformed peak shapes. Then the superimposed signals are used to construct final spectral/imaging results. The superimpose Fourier Transform method in this invention applied to spectroscopy and imaging can narrow Fourier transformed peak width by half and bring about double of peak intensity. It is equivalent to produce the same effects by doubling optical path length of an interferometer or increasing doubly strength of a static magnet; alternatively, reduce half of sampling time for the same resolution on a same instrument.
