Improvement of spectral resolution by signal padding method in the spatially modulated Fourier transform spectrometer based on a Sagnac interferometer
To increase the FFT resolution, we add zero padding to the end of sampled data. What if we didn't add the zeroes at the end of the data, but copy the same
