摘      要：A curved multiplexing method based on the curved computer-generated hologram (CCGH) is proposed theoretically and demonstrated experimentally to increase field of view (FOV) and spatial bandwidth. Point source method is used to calculate the CCGH. Curved multiplexing method can be used to reconstruct different 3D objects at the same position by bending a composed hologram which is synthesized of several CCGHs with different central angles. Numerical simulations and optical experiments demonstrate that the method is feasible. It could have a good prospect by combining with the curved display screen and flexible display materials.
