Background:

Traditional holographic displays often suffer from limited viewing angles, restricting immersive 3D experiences.
Increasing the effective space-bandwidth product is crucial for displaying complex holographic content with high fidelity.

Purpose of the Study:

To develop a wide-angle holographic display system with extended viewing angles in both horizontal and vertical directions.
To enhance the effective space-bandwidth product of the holographic display system.
To achieve fast and synchronized displaying of holographic data for real-time 3D visualization.

Main Methods:

A holographic display system was constructed using six spatial light modulators (SLMs) arranged in a circle.
