Holography and CGH

Adaptive Contrast Enhancement in Computer-Generated Holography Using Nonlinear OptimizationThis study introduces an advanced nonlinear exponential merit function to enhance the contrast and dynamic range of computer-generated holography (CGH). By integrating adaptive energy redistribution into the Gerchberg–Saxton (GS) algorithm, the method selecti…

Non-Convex Optimization for Inverse Problem Solving in Computer-Generated HolographyComputer-generated holography is a promising technique that modulates user-defined wavefronts with digital holograms. Computing appropriate holograms with faithful reconstructions is not only a problem closely related to the fundamental basis of holography but also …

Polarimetric Calibrated Robust Dual-SLM Complex-Amplitude Computer-Generated HolographyLiquid crystal on silicon (LCoS) is a widely used spatial light modulator (SLM) in computer-generated holography (CGH). However, the phase-modulating profile of LCoS is often not ideally uniform in application, bringing about undesired intensity fringes. In this …

Coherence Study on the Image Properties of Holographic DisplayCoherence properties of different light sources and how they affect the image quality of holographic display are investigated. Temporal coherence is related to the intrinsic spectrum bandwidth of the light source, while spatial coherence can be affected by the size of the light source an…
