摘要:

The autoregressive spectral estimation in Fourier transform spectroscopy is examined experimentally in terms of the phase error due to mislocating the zero path difference. Through the nonlinear processing of interferogram, the phase error results in a spectral distortion which somewhat differs from that in the conventional Fourier analysis. A way to reduce the distortion is presented.
