AB - A method of digital holographic imaging for strong diffuse-reflective metal surface is presented. For a strong diffuse-reflection object, the DC term of Fourier spectrum of the hologram is removed by subtracting the patterns the reference beam and object beam from the hologram, which effectively eliminates the influence of the zero-order of the spectrum image on actual information. In view of the more extensive area of Fourier-spectrum region of the hologram for a diffuse reflection object, the spectrum filtering windows is taken as a half area of the Fourier-spectrum region. According the removal of the zero-order term and the use of the half area of filtering windows, the reconstruction imaging for the surface of an alloy plate is achieved, in which both amplitude and phase images are obtained, respectively.
