摘要

In this Letter, we introduce a multiplexing encoding method with a bandwidth constraint strategy to realize a color dynamic holographic display based on complex amplitude modulation (CAM). The method first uses the angular spectrum method (ASM) with a bandwidth constraint strategy to calculate the diffracted wavefronts of red, green, and blue channels. Then the diffracted wavefronts of three channels are synthesized into a color-multiplexed hologram (CMH) based on the double-phase method after they interfere with off-axis reference lights. The color 3D objects can be reconstructed when the combination of red, green, and blue lights is used to illuminate the double-phase CMH, and a 4f system with a slit filter is introduced to extract the desired spectrums. Numerical simulations and optical experiments are performed to verify the effectiveness of the proposed method and the results show that it can achieve a color holographic display with high quality. Our proposal is simple and fast, and the display system is compact. It is expected that our proposed method could in future be widely used in the holographic field.
