A holographic method for displaying large-scale three-dimensional (3D) portrait is put forward. The method is based on the theory of Fresnel hologram and holographic stereogram, resolving the problem that the reconstruction window does not accord with observation field-of-view. Using laser as a recording and reconstruction source, the hologram experiment is carried out. By this method, 3D portrait hologram with a large scale and large depth-of-field is made, which can be reconstructed by laser.
