High-resolution optical coherence tomographic imaging of biological samples and in vivo biological tissues can be realized by full-field optical coherence tomography (FF-OCT). One of the main problems in FF-OCT is how to get the tomographic images from multiple phase shift interference patterns by the Hilbert transform. With the Matlab software used, the image quality was simulated with five main Hilbert transforms, 1D Hilbert transform and four kinds of 2D Hilbert transform including (total Hilbert transform, partial Hilbert transform, single orthant Hilbert transform and bi-orthant Hilbert transform). The results show that compared with that obtained by the 1D Hilbert transform, the image contrast by the 2D Hilbert transform increases by about 10%.
