Adaptive Contrast Enhancement in Computer-Generated Holography Using Nonlinear Optimization

1 March 2025

Adaptive Contrast Enhancement in Computer-Generated Holography Using Nonlinear Optimization This 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)...

Non-Convex Optimization for Inverse Problem Solving in Computer-Generated Holography

9 July 2024

Non-Convex Optimization for Inverse Problem Solving in Computer-Generated Holography Computer-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...

Polarimetric Calibrated Robust Dual-SLM Complex-Amplitude Computer-Generated Holography

1 July 2023

Polarimetric Calibrated Robust Dual-SLM Complex-Amplitude Computer-Generated Holography Liquid 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...

Coherence Study on the Image Properties of Holographic Display

Coherence Study on the Image Properties of Holographic Display Coherence 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...
