High-resolution demodulation of interference envelope peak at arbitrary positions by warped discrete Fourier transform
We propose a novel approach to address the high-resolution problem for analyzing the peak position of an interference envelope in vertical-scanning wideband interferometry. Nonlinear envelope demodulation cannot be performed for arbitrary interference fringes because the envelope peak positions fluc...
