The conventional phase-shift methods in acquiring initial phase under the impact of linear-shift error are analyzed
and the ability of a fixed step algorithm to restrict the linear phase-shift error is researched by frequency domain and spatial domain analysis methods. The emalation model of a Complex Spectral Optical Coherence Tomography(CSOCT) spatial analysis for linear phase-shift is established
and the results are given in accordance with emulation in spatial domain and experiment. The analysis indicates that five frame phase-shift method impacts real structures of the sample in a least degree
restricts mirror image best and obtains images of the sample in 100% range.
