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.
