摘要：
The phase correction process is usually necessary in the calculation of the Fourier transform spectrum. We propose one improved method to calculate the phase-corrected Fourier transform spectrum. By omitting the interpolation calculation and reducing two fast Fourier transform (FFT) operations to only one, high computation efficiency and concise algorithm structure are achieved.
