Weighted Constraint Iterative Algorithm for Phase Hologram Generation
A weighted constraint iterative algorithm is presented to calculate phase holograms with quality reconstruction. The image plane is partitioned into two regions where different constraint strategies are implemented during the iteration process.

Binary Computer-Generated Holograms by Simulated-Annealing Binary Search
The binary computer-generated hologram (BCGH) has attracted much attention recently because it can address the high-speed binary spatial light modulator (SLM), such as a digital micromirror device (DMD) SLM.

Compression of Phase-Only Holograms with JPEG Standard and Deep Learning
It is a critical issue to reduce the enormous amount of data in the processing, storage and transmission of a hologram in digital format. In photograph compression, the JPEG standard is commonly supported by almost every system and device.

High Resolution Multiview Holographic Display Based on the Holographic Optical Element
Limited by the low space-bandwidth product of the spatial light modulator (SLM), it is difficult to realize multiview holographic three-dimensional (3D) display.

Accurate Hologram Generation Using Layer-Based Method and Iterative Fourier Transform Algorithm
Random phase is always added to the object to diffuse the object light in computer-generated holograms. However, this addition causes considerable speckle noise in the reconstructed image. For improving the speckle noise problem, we propose a new method,

Application of Kinoform CGHs to an ID Tag System
In this paper, we successfully apply multilevel kinoform computer-generated hologram (CGH) patterns, which are recorded on a fine texture paper by a photo printer, into the hologram identification (ID) tag system.
