The computer generated Fresnel hologram of a complex three-dimensional (3D) object is synthesized based on a two-dimensional (2D) color image and a stereo matched depth map. The intensity of the color image is divided into multiple slices based on the depth map. The depth value of each slice is transformed into the distance of Fresnel diffraction. According to the principle of tomography, the hologram of the whole 3D scene can be achieved with the single step Fresnel diffraction method. The results show that the method can record and reconstruct the complex 3D object correctly. Intensity superposition method is used to suppress the speckle noise in the reconstructed images, which improves the representation quality significantly.
