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 direct......

Noise addition is a simple but effective method for generating a phase-only hologram (POH) of an object. Briefly, the intensity image of an object is added with random phase noise and converted into a digital Fresnel hologram. Subsequently,......

Computer-generated holography(CGH) is a technique for converting a three-dimensional(3D) object scene into a two-dimensional(2D), complex-valued hologram. One of the major bottlenecks of CGH is the in...

Past research has demonstrated that if the intensity image of an object is uniformly down-sampled and converted into a Fresnel hologram, the phase component alone will be sufficient to reconstruct the source image. However, due to down-samp......

Sub-lines are one-dimensional diffraction patterns representing the light beams emerging from horizontal planes of an object image. Past research has demonstrated that the sub-lines can be encapsulated as a multi-bank filtering process, and......

Past research has demonstrated that a phase-only hologram can be obtained by down-sampling the intensity image of the object scene prior to the generation of the hologram. In this Letter, we extend the method to the generation of binary pha......

Past research has demonstrated that a sampled phase-only hologram (SPOH) is capable of representing an image without the magnitude component of the hologram. At present, an SPOH can only record and reconstruct a single source image. In this......
