In binary computer-generated hologram, the optimization processing is inevitable to reduce coding error. Although Gerchberg-Saxton (GS) method is a powerful tool, the optimized pattern might be trapped in local minimum solutions. This paper presents an introductory comparison of the GS method with the completely optimized pattern obtained by the complete survey method.
