A method for restoring missing sampling points in an array spectrometer leverages the advantages of Fourier interpolation. By adding high-frequency zero values ​​in the frequency domain, it reduces the sampling interval of spectra without missing points, thus increasing the amount of sampled data. In principle, if the original data has sufficient sampling density, Fourier interpolation offers higher accuracy compared to local interpolation. This invention proposes utilizing the distribution characteristics of spectral peaks to reset the sampling density of the original data. After meeting the interpolation prerequisites, it extracts higher-density Fourier interpolations to compensate for the sampling deficiencies in the original data, obtaining estimates with higher accuracy than linear interpolation and spline interpolation. The benefits of this invention are twofold: firstly, it obtains higher-accuracy completed values; secondly, because it does not alter the frequency distribution characteristics of the spectrum, it ensures the processing accuracy of the derived data.
