Paper Abstract

Non-scan holographic spectroscopy is a novel type of Fourier transform spectroscopy (FTS) which frequency modulation is implemented spatially. By the analysis of the general model of the interference of two pre-dispersing beams, it is found first time to our knowledge that the spectral resolving power of the non-scan FTS is determined by the spectral resolving power of these two coherent beams and the fringe number recorded and used for reconstruction of spectrum. As a special case, the spatial heterodyne technique with diffraction gratings used as the pre-dispersers of the coherent beams is stressed and investigated. It is shown that the symmetrical aliasing between the two side spectral regions of the harmonic spectral component can be eliminated with a 2D Fourier transform. The optical experimental results that are agreement with theoretical analyses are given.
