Computer holography is based on advanced computer technology and the basic principle of wave optics, and it is widely employed in many optical fields. In the holographic display, both display systems and encoding methods of computergenerated hologram have effects on the reconstructed image quality. The high coherence of light source causes laser speckle noise that degrades modulation quality severely. The partially temporal coherent light (PTCL) has been applied to holographic reconstruction to reduce speckle noise in display systems, while the encoding methods of computergenerated hologram (CGH) based on PTCL have not been reported. We propose a novel method to encoding CGH, in which a PTCL with a broadband continuous spectrum is used to illuminate the object image.
