Digital holographic illumination using a single phase-only computer-generated hologram

Year: 2024

Type: article

Abstract: This research investigates approaches for optimizing a single phase-only computer-generated hologram (CGH) for digital holographic illumination, with a focus on reducing color dispersion and improving perceived image quality. It explores coherence, speckles, and the impact of hologram sizes on the performance of digital holographic illumination. The influence of multi-wavelength light sources and their coherence characteristics is analyzed, addressing trade-offs between the speckle contrast and image sharpness. Additionally, the role of liquid crystal on the silicon (LCoS) spatial light modulator (SLM) size in balancing resolution and noise reduction is explored. The findings establish a foundation for advancing digital holographic illumination systems, offering scalable solutions for applications in smart lighting and energy-efficient displays.
