| Abstract: | This paper describes a method for converting a complex Fresnel hologram into a phase-only hologram that can be embedded with large amount of data.Briefly,each row of pixels in the hologram is scanned sequentially in a left-to-right direction.The magnitude of each visited pixel is set to a constant,and its phase is embedded with the data.Subsequently,the error is diffused to the neighborhood pixels.The phase hologram realized with such means,which is referred to as the data-embedded-error-diffusion(DEED)hologram,is capable of preserving high fidelity on the content of the hologram and the embedded data. |
