We proposed a holographic 3D display with a convex parabolic mirror to enlarge the viewing zone. However, huge calculation time is required for the diffraction calculation considering the parabolic mirror reflection. Here, to reduce the calculation time, a holographic stereogram approach is proposed. By dividing the hologram surface, paraxial approximation is satisfied individually, which leads to the fast calculation using a fast Fourier transform.
